Depending on moisture dew point measurement absolute error, the Analyzer with ±0,25°С error will be referred below as a working standard, and the Analyzer with ±1°С error – as a working measuring means. The Analyzer can be operated and maintained only by qualified personnel specially trained at the company-manufacturer.

1 DESCRIPTION OF ANALYZER

1.1 PURPOSE 1.1.1 “CONG−Prima−4P” moisture and hydrocarbons analyzer is intended for measuring moisture dew point temperature and hydrocarbons condensation temperature in natural gas of the composi-tion in compliance with ОSТ 51.40−93 “Natural combustible gases delivered and transported via main pipelines. Specifications” at working pressure.

Measurements can be carried out in other gases not aggressive to the component parts of the Ana-lyzer contacting with gas atmosphere being measured. Besides, the Analyzer can be used as working standard for calibration and testing of working means used to measure moisture dew point temperature with dew point measurement absolute error of ±0,5°С and higher.

ATTENTION! When the Analyzer is used as a working standard, measurements shall be carried out in gas atmos-pheres without admixtures condensing earlier than moisture.

1.1.2 The Analyzer is used for:

▪ periodic control of moisture and hydrocarbons dew point temperature (dew point) at gas metering stations, underground storing and drying stations for natural gases etc.;

▪ functional check of stationary hygrometers; ▪ calibration of hygrometers and wet gas generators.

1.1.3 The Analyzer can be used in gas, oil & chemical industries as well as in metallurgy, power and instrument-making industries etc. for quality check of technological processes by moisture and hydrocarbons dew point parameter.

1.1.4 The Analyzer is made explosion-proof and has “explosion-proof enclosure” explosion protec-tion type according to GOST_Р_51330.1, “compound sealing (m)” explosion protection type - ac-cording to GOST Р 51330.17 and 1ExmdIIAT5 explosion protection marking. It can be operated in hazardous areas according to GOST Р 51330.13, part 7.3 of Electric Installation Code and other normative documentation regulating the use of electric equipment in hazardous areas.

1.3 DESCRIPTION OF DESIGN 1.3.1 Functionally, the Analyzer comprises the following complete units:

▪ primary information sensor (PIS); ▪ electronic unit (EU); ▪ self-contained power source; ▪ gas preparation system (GPS).

IMPORTANT!

Some modifications in the Analyzer configuration that do not affect its technical characteristics are possible when the latter is delivered to customers. These modifications are specified in the Ana-lyzer data card, section 4 “Complete set”.

1.3.2 PIS is intended to realize cooling, stabilizing and heating modes using commands from EU as well as to generate electric signals corresponding to temperature and photo signal level in electronic unit.

PIS is an optofiber transducer that allows measuring of output signal values both when moisture ap-pears or disappears on its sensing element. PIS drawing is shown in Appendix B. Primary information sensor incorporates housing 1, meter 2, thermal sensor 3 for measuring sensing element (SE) temperature, thermal sensor 4 for measuring sensor housing temperature, three-cascade thermal electronic battery 5 and optical fiber 6. Meter 2 comprises LED 7, photodiode 8 and light guide 6. When the light guide and gas flowing around it are cooled to the saturation temperature at working pressure of the three-cascade thermal electronic battery, condensate precipitates on the light guide bended part surface. The photo diode registers reduction in the intensity of radiation coming from


6

LED to the light guide. This results in the command to start heating and register condensation tem-perature using thermal sensor 3, which is mated with the light guide bended part. When the light guide and gas flowing around it are heated above the saturation temperature, con-densate evaporates from the light guide bended part surface, the photo diode registers increase in the radiation intensity and the built-in thermal sensor registers evaporation temperature. To make measurement of low dew point values possible (see i.1.4.1), an additional channel for cooling gas is provided in PIS. Working gas preliminarily passed through the external cooler oper-ated on throttle effect due to pressure drop is used as cooling gas. It is possible to cool the sensor using other coolants.

1.3.3 Electronic unit (EU) has an explosion protected case and is intended for:

▪ measuring primary signals and their normalization; ▪ control over dew point measurement process and other modes taking into account pa-

rameters specified by software; ▪ displaying measured values on the built-in indicator.

1.3.4 The Analyzer is equipped with self-contained power source – VYMP5.087.023 battery unit (BU).

Basic technical characteristics of battery unit: ▪ type of batteries – VH4000 4/ 3 A x 1, 2 V “VARTA” (nickel – metallic hydride N-

iMH); ▪ number of cells – 19; ▪ nominal voltage – 24 V; ▪ electric capacity – 4 Аh; ▪ life (limited by the number of charge/discharge cycles) – 500 cycles.

Table 1 shows dependence between the Analyzer operating time in an independent mode and bat-tery unit charge rate:

Table 1

BU charge rate (%) Analyzer operating time (hours) 100 2 – 4* 75 1,5 – 3 50 1 – 2 25 0,5 – 1

________________ *– operating time depends on dew point temperature value being measured.

Battery unit is placed in a special compartment of the Analyzer housing closed by a cover (pos.17, Appendix А).

1.3.5 Gas preparation system (GPS) is positioned in the Analyzer housing (see Appendix А). GPS enables filtration of analyzed gas from mechanical admixtures, control over gas flow rate through measuring chamber and measurement of pressure in measuring chamber.

The Analyzer is connected to analyzed gas supply line via inlet (pos. 1, Appendix А). Tubes connected to unions (pos. 3) and (pos.3) are used for discharging analyzed gas and for blow-ing down sampling line, correspondingly. Components of gas preparation system are as follows:

▪ measuring chamber (pos.7); ▪ valve used to control gas flow rate via measuring chamber (pos.4); ▪ cock used to blow down gas supply line (pos.15); ▪ filter used to remove mechanical admixtures from sample (pos.11); ▪ manometer (pos.5); ▪ flowmeter (pos.6);

1.4.1 The Analyzer measurement lower limit is determined by the operational efficiency of thermal electronic battery (TEB) that provides temperature drop of about 70°С under normal conditions. Relationships between minimum temperature of condensational surface and the Analyzer housing temperature at different working pressures of measured atmosphere are shown in Fig. 2.

1.4.2 The Analyzer is not capable of measuring the dew point below minimum temperature achieved by condensational surface.

Figure 2. Relationships between minimum temperature of condensational surface and DPT housing temperature at different working pressures of measured atmosphere.

The Analyzer is resistant to technological admixtures of natural gas. Its indications remain valid at the following concentrations of technological admixtures vapors:

▪ methanol– up to 1 000 mg/m3; ▪ diethyleneglycol (DEG)– no influence is revealed at concentrations below 5 mg/m3.

Exceeding of the above concentration increases the Analyzer’s indications by more than 1°С.

1.5 CONNECTIONS OF THE ANALYZER

To ensure independent operation of the Analyzer from battery unit (BU), simply connect inlet pos. 1 (Appendix A) to in-situ gas sampling system. For longer (more than 4 hours) operation of the Analyzer external power source should be connected. Explosion-proof connectors pos. 12 and pos. 13 are on front panel of the Analyzer to the left above its indicator. Connector pos. 13 is intended for connecting power source or VYMP5.122.003 charger to the Analyzer. Connector pos. 12 is a technological one. IMPORTANT! To ensure explosion protection when operating the Analyzer in hazardous areas, non-used connec-tors should be closed by special plugs. Circuit diagram for connecting external devices to the Analyzer is given in Appendix C. Connectors under the Analyzer round cover are intended for technological purposes. It is forbidden to open this cover in hazardous areas.

1.6 DISPLAY AND KEYBOARD The Analyzer display is a four-line LCD indicator.

Keyboard is used to control operation of the Analyzer. It is four sealed contacts that are switched using a special magnetic key. Fig. 3 shows location of keyboard magnetic contacts on the Analyzer front panel. Magnetic contacts are switched using a supplied magnetic key. The key acts on the cor-responding magnetic contact within 1-2 seconds. Working with the Analyzer keyboard is described in details in items 1.8 – 1.15.

1 . 7 MEASUREMENT METHOD AND CAPABILITIES OF THE ANALYZER 1.7.1 Condensation method is used when measuring dew point. This method involves measurement of temperature to which it is necessary to cool a wet gas layer adjoining the surface being cooled in order to bring it to a saturated condition at working pressure. The present method corresponds to GOST 20060 “Combustible natural gases. Methods for determining water vapors presence and moisture dew point” and GOST 20061 “Combustible natural gases. Method for determining hydro-carbons dew point temperature”.

The Analyzer provides:

▪ measuring of dew point temperature in mirror (SE) temperature manual control mode; ▪ measuring of dew point temperature in the mode of retaining and stabilization of

specified (manually) condensate film thickness on mirror; ▪ digital indication of measured dew point value (ºС), current mirror temperature (ºС)

and condensate film thickness (% of clean mirror photo signal level); ▪ independent operation from battery within 2–4 hours; ▪ operation from external power source.

1.8 ANALYZER FUNCTIONING ALGORITHM

1.8.1 The Analyzer has two operation modes:

▪ automatic; ▪ manual.

Dew point measurement error in automatic mode corresponds to specified technical characteristics of the Analyzer. Measurement results are displayed on built-in indicator and stored in the Analyzer memory. No standards exist for dew point measurement error in manual mode. Operator determines dew point measurement results using current temperature of the Analyzer mirror at the moment of condensation (evaporation) and, as a result, they are not displayed on indicator. Therefore, manual measurement mode is used to get reference dew point values in analyzed gas.

1.8.2 Operating algorithm of the Analyzer used as a working measurement means in automatic mode.

Initially, gas sample is tested for the presence of hydrocarbons (or other earlier condensable admix-tures) in it. Parameters of moisture and hydrocarbons operating cycles are selected depending on test results. After hydrocarbons are found the Analyzer enters moisture and hydrocarbons dew point one-by-one measurement mode.

b)

Figure 4 – Visualization of moisture dew point measurement process: а) – in natural gas with high content of heavy hydrocarbons; b) – in natural gas with low content of heavy CH.

Therefore, the Analyzer during its operation periodically and automatically controls presence of earlier condensable hydrocarbons in analyzed gas.


11

Figures 4, 5 show characteristic condensation curves for the Analyzer operation on natural gas ob-tained using «CONG-Prima-4» stationary dew point analyzer capable of measurement process visu-alization. Dew point measurement process consists of three basic stages:

▪ stage 1 – warming of mirror and stabilization of its temperature; ▪ stage 2 – cooling of mirror and searching for condensation temperature; ▪ stage 3 – warming of mirror and searching for evaporation temperature.

As it is seen in Fig. 4а, in case content of hydrocarbons in gas is high, first heavy hydrocarbons and then moisture condensate on the Analyzer sensing element when the latter is being cooled. In case hydrocarbons concentration is low or hydrocarbons dew point is lower than moisture dew point, moisture condensates on the Analyzer sensing element (see Fig. 4b) immediately after the lat-ter is cooled. The criterion for formation of condensate film on sensing element is a reduction of level of photo signal registered by the Analyzer optical system. After the Analyzer sensing element is warmed further, first moisture and then hydrocarbons evaporate.

Figure 5. Visualization of hydrocarbons dew point measurement process


12

Figure 6. Visualization of dew-point measurement process using condensate film retention

method When sensing element temperature is being stabilized at 50°С, photo signal level remains un-changed. Therefore, as a result of measurement, condensation curve (photo signal modification curve) is determined. Mathematical processing of the curve allows determining moisture de point. Figure 5 shows hydrocarbons dew point measurement process. Hydrocarbons dew point tempera-ture is calculated as condensation starting temperature (temperature at which photo signal starts to reduce).

1.8.3 Operating algorithm of Analyzer used as a working standard in automatic mode.

Automatic mode for the Analyzers used as a working standard is different to some extent from the mode described in i.1.8.2. The main difference is that to ensure specified accuracy (±0,25°С), moisture dew point is measured in the mode of slow cooling of mirror to condensate formation temperature. After condensation temperature is determined, mirror is warmed in order it could be cleaned from condensed moisture Test cycles are not included in the Analyzer operating algorithm since absence of admixtures con-densing earlier than moisture in measured gas atmosphere is supposed beforehand. Hydrocarbons dew point is not also measured in this mode. In case it is required to measure hydro-carbons dew point (provided it is higher than moisture dew point) the Analyzer should be urged into hydrocarbons measurement mode in compliance with i. 1.9.9. To calibrate dew point measuring working means using the Analyzer it is recommended to inert use inert gases such as air (according to GOST 24484) and nitrogen (according to GOST 24484).

1.8.4 Operating algorithm of the Analyzer in manual mode.

Two kinds of manual dew point temperature measurement are being implemented in the Analyzer: ▪ measurement of dew point temperature in the mode of retention and stabilization of

manually specified condensate film thickness on mirror (SE); ▪ measurement of dew point temperature in the mode of mirror (SE) temperature manual

control.


13

Figure 6 shows dew point measurement process in specified condensate film thickness retention mode. In this case operator manually sets the desired film thickness in percents of clean mirror photo signal level. Measurement is a process of long-term condensate film retention until retention temperature and film thickness are stabilized. Mirror temperature and film thickness current values are controlled using the Analyzer indicator. Film retention temperature is dew point temperature. Figure 7 shows dew point measurement process in mirror (SE) temperature manual control mode. In this case operator manually changes current mirror (SE) temperature. Change of photo signal value characterizing condensate film thickness is a sign of condensation. Current mirror tempera-ture and film thickness values are controlled using the Analyzer indicator.

Figure 7. Visualization of dew point measurement process

Dew point temperature can be determined with a certain degree of validity by making boundary be-tween condensation and evaporation temperatures narrower.

1.9 DESCRIPTION OF USER’S MENU AND CONTROLS OF THE ANALYZER 1.9.1 The Analyzer is switched on after a magnetic key acts on left magnetic contact (see Fig. 3). Indicator then appears as follows:

Moving through menu items is performed using a magnetic key that acts on the upper (bottom) magnetic contact. The selected menu item will have a darker field. To enter the appropriate menu item act with a magnetic key on the right magnetic contact. More details on the Analyzer basic operating modes are given below.

1.9.6 Submenu of Analyzer automatic operating mode.

1.9.6.1 After AUTO item is selected in mode menu or in 30 seconds after system loading the Ana-lyzer enters automatic operating mode. After you act with a magnetic key on the right magnetic contact indicator displays more detailed information on the Analyzer operation in automatic mode.

Data on definite measurement steps (see i.2.5) are indicated in the middle part of indicator instead of main menu items. View of indicator ion this mode is shown below:

Тdp -12,7 Line 1 Т ± 35,0 СН -7,9 F 98,6 TIME Line 2 Тh ± 22 0:17:08 А █

1.9.6.2 Line 1 defines type of the performed measurement cycle and may take the following values:

▪ TEST – test cycle is being conducted at the moment; ▪ MOISTURE – moisture dew point measurement is being conducted at the moment; ▪ СН – hydrocarbons dew point measurement is being conducted at the moment.

1.9.6.3 Line 2 characterizes definite measurement stage:

▪ COND – sensing element (mirror) is being cooled at the moment; ▪ EVAP – sensing element (mirror) is being heated at the moment; ▪ FILM – condensate film retention process is taking place on sensing element (mirror).

1.9.6.4 In this case measured hydrocarbons and moisture dew point temperature values renewed af-ter each successive measurement and time elapsed after the Analyzer ahs been enabled are dis-played in the left part of indicator.

1.9.6.5 Current values in compliance with 2.6 are displayed in the right part of indicator.

To return to the Analyzer main menu act with a magnetic key on the left magnetic contact.

1.9.7 Submenu of Analyzer manual operating mode.

1.9.7.1 After MANUAL item is selected in main menu, automatic measurement mode ceases, mir-ror temperature reaches warming-up temperature, and the Analyzer enters manual sensing element (mirror) temperature control mode. Algorithm for measuring dew point in this mode is described in i.2.6.

1.9.7.2 When working in manual mode measured hydrocarbons and moisture dew point values in the left part of indicator remain unchanged.

In this mode indicator appears as follows:

Тdp-12,7 SELECT Т -1 3,2 СН -7,9 STEP F 91,6 ВРЕМЯ SELECT Тh ± 22 0:17:08 Т M █


16

1.9.7.3 One of the two mirror temperature control modes is selected using upper and bottom mag-netic contacts:

▪ STEP SELECT – allows to change mirror temperature with a specified interval; ▪ SELECT – allows to strictly set definite mirror temperature value.

To enter this or that mode act with a magnetic key on the right magnetic contact.

1.9.7.4 After step-by-step modification of mirror temperature is selected, indicator displays the fol-lowing data:

Тdp-12,7 STEP Т -1 3,2 СН -7,9 0,5 F 91,6 TIME SELECT Тh ± 22 0:17:08 1,0 M █

The second line shows interval value used at the current moment. The bottom line shows new interval value that will become valid after it is confirmed by SELECT item.

1.9.7.5 Pressing upper or bottom magnetic contacts allows to select the below items in cyclic mode:

To change a digit in the selected position act on the right magnetic contact successively from 0 to 9.

1.9.7.6 After the desired interval value is entered, confirm this value by moving a cursor to SE-LECT item. As a result, new interval value will be displayed in the second line of indicator.

1.9.7.7 After the interval is selected, by acting on the right magnetic contact the Analyzer is taken to mirror temperature step-by-step modification mode, starting with a certain specified initial tempera-ture that has to exceed dew point temperature:

Тdp-12,7 WARM.UP Т +30,0 СН -7,9 +30 F 100,0 TIME STEP Тh ± 22 0:47:08 1,0 Р █

Mirror temperature is changed by acting on upper or bottom magnetic contact. Each action on up-per (bottom) contact increases (reduces) mirror temperature by an interval (in °С), shown in the bot-tom line (1°С in the given example). To return to previous level menu act on the left magnetic con-tact.

1.9.7.8 After SELECT Т temperature set mode is selected, operator is able to perform one-step mirror temperature modification from initial to a certain set point. After you act on the right mag-netic contact with a magnetic key, indicator appears the same as previously:


17

Тdp-12,7 WARM.UP Т +30,0 СН -7,9 +30 F 100,0 TIME STEP Тh ± 22 0:47:08 1 °С M █

Using upper and bottom magnetic contacts you may correspondingly increase or reduce mirror ini-tial temperature (+30°С in the given example). Temperature will be reduced or increased with the interval displayed in the bottom line of indicator. Specified initial warming-up temperature will be also changed when working in step-by-step cool-ing mode (see i.i. 2.6.1– 2.6.4). After pressing the right magnetic contact again, you may select the set point temperature to which mirror temperature has to be reduced from initial to the selected set point by one interval. Indicator then appears as follows:

Тdp-12,7 SET Т 30,0 СН -7,9 0,0 F 100,0 TIME SELECT Тh ± 22 0:17:08 -010,0 M █

Set point temperature is selected like interval is selected in 1.9.7.4. After you move a cursor to SE-LECT item and press the right magnetic contact, selected set point value is displayed in the second line of indicator, and current mirror temperature (Т value in the first line of the right part of indica-tor) takes set point value:

Condensate film thickness is selected similar to interval selection in i. 1.9.7.4

IMPORTANT! Condensate film thickness is set depending on sensing element photo signal level that is considered to be 100 %. Therefore, for example, 90 % set point means that the Analyzer mirror will retain condensate film with the thickness corresponding to photo signal reduction from 100 % to 90 %. At the same time with selecting film thickness in this mode mirror retains film with the thickness shown in the second line of indicator (85 % in the given example). Current retention temperature Т and current photo signal value are displayed in the right part of in-dicator. To return to the previous level menu act on the left magnetic contact.

1.9.9 Submenu of hydrocarbons measurement mode.

This operating mode of the Analyzer implements measurement mode in accordance with GOST 20061-84 ”NATURAL COMBUSTIBLE GASES. Method for determining hydrocarbons dew point temperature”. According to this standard starting temperature of hydrocarbons condensation is taken as hydrocarbons dew point. Therefore, when working in this mode, the Analyzer during each measurement cycle fixes tempera-ture at which condensate starts forming on sensing element. Correct use of this mode is only possi-ble provided hydrocarbons dew point exceeds moisture dew point in analyzed gas sample. During operation of the Analyzer it is recommended to use this mode when calibrating hydrocarbons dew point measurement channel (see i.2.8). After you select СН item in the Analyzer main menu and act on the right magnetic contact the Ana-lyzer enters submenu of dew point measurement only by hydrocarbons. When entering СН mode indicator appears as follows:

Тdp-12,7 СН Т +35,0 СН -6,8 F 100,0 TIME ON Тh +27 1:10:28 OFF С

After OFF item is used using upper or bottom magnetic contact and confirmed using the right magnetic contact the Analyzer returns to main menu.

2.4.2 Switching Analyzer on.

Prior to operation make sure that all valves and cocks in the initial position are closed.

2.4.2.1 Starting of the Analyzer is described in i.i. 1.9.1 – 1.9.2.


22

2.4.2.2 Select the required mode of further work in the Analyzer menu (see i. 1.9.5) by acting on upper (bottom) magnetic contact. In case none of the modes is selected within 30 seconds, the Ana-lyzer enters automatic mode of dew point temperature measurement.

2.4.2.3 ” NO” is indicated instead of measured values during the first test cycles conducted after starting. After measurement (by moisture and/or hydrocarbons) is conducted, measured dew point value is displayed on indicator on the corresponding icon place (°С not displayed on indicator).

No control is required when the Analyzer is being operated in automatic mode. Control procedures over the Analyzer operation in other modes are described in i. 1.9.

Now gas preparation system is in operating condition. Cock pos. 15 is only slightly opened to blow connecting pipeline down.

2.5 ANALYZER OPERATION IN AUTOMATIC DEW POINT TEMPERATURE MEAS-UREMENT MODE 2.5.1 Automatic dew point temperature measurement mode is the Analyzer main operation mode.

After the Analyzer is enabled in accordance with i. i. 1.9.1– 1.9.2, enter submenu of the Analyzer automatic operation mode AUTO. Indicator then will display additional data on the Analyzer op-eration in this mode.

2.5.1.1 Measured instant moisture and hydrocarbons dew point temperature values and time elapsed from the moment of the Analyzer starting are displayed in the left part of indicator. ”NO” is indi-cated instead of measured values during the first test cycles conducted after starting. After meas-urement (by moisture and/or hydrocarbons) is conducted, measured dew point value is displayed on indicator on the corresponding icon place (°С not displayed on indicator).

In case hydrocarbons are not found in analyzed gas sample or hydrocarbons dew point temperature is lower than moisture dew point temperature, ”NO” is indicated in the left part of indicator oppo-site CH. In case the Analyzer is used as a working standard means, ”NO” is always indicated in the left part of indicator opposite CH. In case moisture dew point temperature in analyzed gas sample is lower than measurement range, the Analyzer low measurement limit (minus 30) is indicated in the left part of indicator opposite Тdp.

2.5.2 Data on the Analyzer current status according to i. 1.9.6 are displayed in the middle part of in-dicator. Current measurement cycle characteristics are indicated in the upper line.

2.5.2.1 For the Analyzer operated as a working measurement means first TECT (TEST) is dis-played in the upper line indicating that the Analyzer performs test measurement cycle in compliance with the operating algorithm.

During test cycle gas sample is tested for hydrocarbons presence. Then the Analyzer starts measurement cycle by moisture, MOISTURE is displayed in the upper of indicator. In case hydrocarbons are found during test cycle, after measurement by moisture is over the Ana-lyzer starts measuring hydrocarbons dew point, and CH appears in the middle part of indicator. Af-


23

ter the measurement is over measured hydrocarbons dew point temperature value is displayed on indicator. Then the Analyzer starts one-by-one measuring of moisture and hydrocarbons dew points, and measurement cycle being conducted is displayed in the upper line of indicator. In case hydrocar-bons are not found in test cycle, only moisture measurement cycle is being performed by the Ana-lyzer. After 10 measurement cycles by moisture are over or in case moisture dew point sharply (by more than 3 degrees) changes, the Analyzer again starts performing test cycle.

2.5.2.2 Gas sample is not tested for the Analyzer operated as a working standard means. When TEST appears, the Analyzer is adjusted and tested for serviceability. Then the Analyzer starts measuring moisture dew point and MOISTURE is displayed in the upper line of indicator. After the measurement is over moisture dew point temperature value is displayed on indicator, and the next measurement cycle begins.

Current measurement stage characteristic is displayed in the bottom line of the middle part of indi-cator. Corresponding data appear in the bottom line depending on processes taking place on the Analyzer sensing element (mirror). When the sensing element (mirror) is being warmed up at constant temperature prior to measure-ment, WARM.UP is displayed in the bottom line of the indicator. When the mirror is being cooled at constant rate, COND is displayed in the bottom line of the indi-cator. The mirror is being cooled until condensation temperature is registered. After condensation temperature has been registered, the mirror is being heated, and EVAP is dis-played in the bottom line of the indicator. The mirror is being heated until its temperature reaches warming up temperature. During test cycle, when condensate film is being retained on mirror, FILM is displayed in the bot-tom line of indicator.

2.5.3 Current parameters of the sensing element and the Analyzer status data are displayed in the right part of the indicator.

2.6 ANALYZER OPERATION IN MANUAL DEW POINT TEMPERATURE MEASURE-MENT MODE Manual dew point temperature measurement mode is provided in order to control the Analyzer ser-viceability and assess validity of measurements in automatic mode. Manual mode submenu is entered by selecting MANUAL item in the Analyzer main menu and pressing the right magnetic contact. Mirror temperature can be changed using two possible ways:

▪ step-by-step, with selected interval; ▪ fixed, up to selected mirror temperature.

In both cases mirror temperature will be changing up to certain initial temperature set by operator. For correct operation of the Analyzer initial mirror temperature (set point temperature) shall exceed predicted dew point temperature by not less than 10 °С. When selecting mirror initial temperature, one shall take into automatic mode measurement results.

2.6.1 Mirror initial temperature is set according to i. 1.9.7.8. To do this select SELECT Т submenu by pressing the right magnetic contact. Then increase or reduce mirror initial temperature by press-ing upper or bottom magnetic contacts, correspondingly. Each action of magnetic key on the contact increases (or reduces) initial temperature by 1°С. Mirror initial temperature by default is + 30°С.

2.6.2 After mirror warm up initial temperature is selected, repeat pressing of the right magnetic con-tact allows to set temperature to which mirror shall be cooled (heated). Desired temperature is set according to the procedure described in 1.9.7.8. The Analyzer starts processing the set temperature after you place cursor on SELECT item and confirm the set point by pressing the right magnetic contact.


24

2.6.3 In order to enter step-by-step cooling mode press the left magnetic contact to return to previ-ous level menu and select STEP SELECT item. Set mirror temperature change interval value ac-cording to the procedure described in i. i. 1.9.7.4 – 1.9.7.7,

To measure dew point, press the right magnetic contact again. Measurement method in the mode of fixed mirror temperature change is as follows:

▪ taking into account the results of dew point temperature measurement in automatic mode, in SET submenu set temperature to which the mirror shall be cooled and that has to exceed values measured in automatic mode (these values are displayed in the left part of indicator) by (3 – 5) °С;

▪ place cursor SELECT item and press the right magnetic contact. The Analyzer will cool the mirror to set temperature. Data on current temperature Т and photo signal F of the sensing element (mirror) displayed in the right part of indicator allow to judge about condensate precipitation on the mirror. In case photo signal F remains at the level of 100 % for some time, no moisture condensation is observed on the mirror at set tem-perature;

▪ in SET submenu set temperature that is lower than previous one by (5 – 7) °С and cool the mirror to set temperature. In case set temperature is lower than dew point tempera-ture, moisture will condensate on the mirror and photo signal F will start reducing;

▪ by successively increasing or reducing set temperature and by making interval between temperatures at which condensation (reduction of photo signal F) and evaporation (in-crease of photo signal F) is taking place smaller, difference between these temperatures is achieved to be not more than (2 – 3) °С. Average value between these two tempera-tures is considered to be the dew point temperature.

2.6.4 Measurement method in the mode of step-by-step mirror temperature change is as follows:

▪ set 5,0 °С interval in STEP SELECT submenu according to the procedure described in i. 1.9.7.4;

▪ place cursor on SELECT item and press the right magnetic contact. The Analyzer will enter mirror temperature step-by-step change mode;

▪ successively press bottom magnetic contact with 30 s interval until condensation starts on mirror (reduction of photo signal F);

▪ increase mirror temperature by pressing upper magnetic contact. In case no evaporation (increase of photo signal F) occurs then within 1-2 minutes, increase current mirror temperature by one interval more;

▪ reduce temperature change interval to 3,0 °С and proceed as above; ▪ in the end set (1 – 0,5)°С interval and determine condensation and evaporation tem-

peratures taking into account photo signal F. Average value between these two tempera-tures is considered to be the dew point temperature.

2.7 ANALYZER OPERATION IN CONDENSATE FILM RETENTION MODE 2.7.1 Film retention mode is used in case earlier condensable admixtures are not present in gas. This method allows to determine moisture dew point temperature with a high level of validity.

2.7.2 After you select RETENTION item in main menu and enter it by pressing the right magnetic contact, the Analyzer enters mirror temperature adjustment mode.

2.7.3 Initial temperature set in SELECT Т manual mode submenu is being sustained on the mirror. After you press the right magnetic contact gain, the Analyzer enters condensate film thickness specification and mirror temperature adjustment mode. Condensation film thickness is set in accor-dance with i. 1.9.8.

2.7.4 Measurement method in this mode is as follows:

▪ 80 % value is set in SET submenu of RETENTION mode. This means that the Ana-


25

lyzer will stabilize mirror temperature so that current photo signal F could stabilize at the level of 80 % of maximum level (100 %). And this, in its turn, means that the film retained on the mirror is of such thickness that results in sensing element photo signal reduction from 100 % to 80 %;

▪ after all transients have died out, the film thickness (current level of photo signal F) stabilizes at 80 % level. Current mirror temperature T is also being stabilized at the same time with the film thickness stabilization. Average value of current mirror temperature after the film has been stabilized is considered to be the dew point tempera-ture;

▪ in case the film thickness and current mirror temperature are not stabilized with t time, reduce the film thickness by 5 % (set 85 % value). If it does not have a posi tive effect, reduce the film thickness by 5 % more (set 90 %). In case current photosig-nal F or current temperature Т are not stabilized, the Analyzer cannot be operated in this mode.

2.8 ANALYZER OPERATION IN HYDROCARBONS MEASUREMENT MODE 2.8.1 The Analyzer is shifted to the measurement mode only by hydrocarbons in accordance with i.1.9.9. As a result, the indicator will display additional data on the Analyzer operation in this mode.

2.8.2 Measured instantaneous values of hydrocarbons temperature dew point are displayed in the left part of the indicator. Since moisture dew point is not measured in this mode, NO is constantly displayed in Тdp line. After each new measurement is performed, new measured dew point value (°С not displayed on the indicator) is displayed in СН line. Time elapsed after the Analyzer has been is started is displayed in the bottom line.

In case hydrocarbons dew point temperature in analyzed gas sample is lower than the measurement range, the Analyzer lower hydrocarbons measurement limit is indicated in the left part of the indica-tor opposite СН – minus 30.

2.8.3 Data on the Analyzer current status are displayed in the middle part of the indicator.

Similar to automatic mode characteristic of the current measurement cycle is displayed in the upper line. Therefore, CH is displayed in the upper line during operation in constant hydrocarbons dew point measurement mode. Characteristic of the current measurement stage is displayed in the bottom line of the middle part of the indicator. Depending on the processes taking place on the Analyzer sensing element (mirror), appropriate data are displayed in the bottom line. When the sensing element (mirror) is warmed up at constant temperature prior to measurement cy-cle, WARM is displayed in the bottom line. This stage is intended for cleaning the mirror prior to measurement. When the mirror is being cooled at constant rate COND is displayed in the bottom line. The mirror is being cooled until condensation temperature is registered. After condensation temperature has been registered, the mirror is being heated, and EVAP is dis-played in the bottom line of the indicator. The mirror is being heated until its temperature reaches warming up temperature.

2.8.4 Current parameters of the sensing element and the Analyzer status indicators are displayed in the right part of the indicator in accordance with i.1.9.3.

2.9 ANALYZER OPERATION FROM EXTERNAL POWER SOURCE VYMP5.122.003 charger is recommended to be used as an external power source. Appendix 3 shows the diagram for connecting an external power source to the Analyzer. When the Analyzer is being operated from an external power source to reduce consumption current (voltage drop across power leads) it is recommended to turn battery charging off (see i.3.2.2).


26

2.10 ANALYZER OPERATION UNDER DIFFERENT WORKING CONDITIONS To provide continuous and successful operation of the Analyzer without regular servicing it is re-quired to thoroughly follow the requirements to sampling place (see i. 2.2.4). If these requirements are not fulfilled, it may cause contamination of the Analyzer measuring chamber by aerosol and mechanical admixtures. All these factors being combined may cause failures in the Analyzer read-ings and the need for more frequent regular servicing. Peculiarities of the Analyzer applications un-der different operating conditions are given below.

2.10.1 Analyzer operation on main pipelines.3

Operating conditions: gas, having been completely cleaned, drained and prepared for transportation. All-the-year-round operation, ambient temperature – minus 40°C…+40°C, gas temperature – +20°C…+40°C; pressure – 5…8 MPa; specific deviations of moisture dew point – minus 20°C… minus 5°C at working pressure; component gas composition – hydrocarbons (with dew point not exceeding moisture dew point by more than 5°C), concentration of methanol vapors – up to 60 mg/m3, concentration of diethyleneglycol vapors – 0.0 … 0.02 mg/m3, mechanical admixtures – standard. Analyzers, working on gases of main pipelines and that have passed all preparation stages for transportation, practically need no regular servicing. In case diagnostic messages are displayed on the indicator, preventive measures shall be taken to restore the Analyzer serviceability, and other-wise the manufacturer shall be consulted.

2.10.2 Analyzer operation at underground storing gas stations (USGS) and gas fields (GF).

Operating conditions: gas from underground storages with layer pressure of up to 15MPa, immedi-ately after gas drying stations. Season operation – autumn-winter-spring, ambient temperature – mi-nus 40°C…+ 15°C; gas temperature – minus 7°C …+12°C, pressure – 2.5…7.5 MPa; specific de-viations of moisture dew point – minus 25°C …+3°C at working pressure; component gas compo-sition – hydrocarbons (with dew point exceeding moisture dew-point), concentration of diethylene-glycol vapors – 0.0…0.2 mg/m3, mechanical admixtures – no data. Main features of operation of devices at USGS are as follows:

▪ harmful combination of some factors (low ambient temperature with high possibility of peak values by moisture – up to +4°C at relatively low gas temperature – 0°C … +10°C);

▪ considerable deviations in gas flow, appearance of water-methanol jams during forced warming of hydrated blocks (in fittings) or changing of filter chucks in gas separation units as well as getting out of a big amount of humidity at the beginning and at the end of gas sampling from underground storage. All these may result in moisture and other components entering the diffusion zone of the Analyzer sampling device.

Therefore, when conducting measurements, special attention shall be given to the strict control of sample validity. Sharp increase of moisture dew point values being measured indicates that con-densed moisture entered measuring chamber or sampling line is overcooled. So special attention shall be also given to meet the requirements both to the location of the Analyzer on pipeline (see i. 2.2.5) and to the location of sample taking as regards to technological devices initiating water or hydrate jams appearance on pipeline during operation. The presence of moisture or other gas components (DEG, TEG drops, methanol etc.) in gas sam-pling system and measuring chamber can be determined by the following signs:

▪ uneven changes in the Analyzer readings both in plus and minus directions and then – smooth restoring of dew point initial value;

▪ the Analyzer reading by moisture are clearly too high (moisture dew point exceeds gas temperature) in case water is brought in, or they are too low in case a sorbent (methanol,


27

DEG or others) is brought in.

In this case it is recommended to thoroughly blow down both gas supply line and measuring cham-ber by gas flow. The Analyzer readings are quickly normalized and become valid in some time. Gas flow during measurement shall not exceed (1 – 1,5) normal l/min (gas flow shall provide appearance of soap bubbles; if they do not appear, gas flow is too high or low). You should not set gas flow abruptly or too high as it may cause contamination of the Analyzer measuring chamber by dirt, moisture or sor-bents.

2.10.3 Special features of low dew point temperature measurement

As it was described in i. 1.4.1, the Analyzer low measurement limit is determined by the operation efficiency of thermal electronic battery. Therefore, to measure low dew point values the Analyzer sensor housing temperature shall be reduced to the level enough to provide effective operation of the battery. At the same time temperature to which PIS housing shall be reduced depends on meas-ured atmosphere pressure and gas composition. Figure 2 shows this dependence for natural gas. Different coolants (water, nitrogen, carbon dioxide etc.) passing via additional cooling stage of the sensor (see Appendix B) or natural gas immediately throttling can be used for cooling the sensor.

2.11 SAFETY REQUIREMENTS 2.11.1 General provisions

2.11.3 It is forbidden to use the Analyzer to measure parameters of atmospheres aggressive to the materials in contact with measured atmosphere.

2.11.4 The Analyzer can be operated only provided there is an accident prevention instruction ap-proved by the head of the consumer-enterprise and taking into account special features of the Ana-lyzer application in a certain technological process.

2.11.5 The Analyzer belongs to class 01 according to GOST 12.2.007.0 ССБТ by its electric safety method.

2.11.6 The Analyzer shall be connected and disconnected from the pipeline only after a cock on gas sampling device is closed.

After restoring test cycle is performed, battery is ready to operation.

3.2.2.2 BU maintenance during Analyzer operation.

During the Analyzer operation the following recommendations shall be followed in order to make BU life longer and to conserve its electrical capacitance:

▪ do not store the Analyzer at high and low temperatures. Recommended storage tem-perature is from +15 to +25 0С (limit values – from minus 10 to + 45 0С);

▪ prior to each use of the Analyzer from independent power source (BU) control BU charge level. Relationship between the Analyzer operating time in independent mode and BU charge level is shown in i.1.3.4;

▪ prior to each full battery charging it shall be fully discharged; ▪ each time after the Analyzer is enabled 8 – 10 times from BU perform restoring test

cycles (see. i.3.2.2.2); ▪ use only a standard charger supplied with the Analyzer for BU charging.

After BU life (500 charge/discharge cycles) is over, you may order new BU at the company-manufacturer (its address and telephone are given on p.2 of the present Manual BU shall be re-placed by the customer as follows:

▪ remove cover from the battery compartment by unscrewing 8 bolts pos. 17 (Appedix A);

▪ disconnect old BU from connector and remove it from the battery compartment; ▪ place new BU in the compartment by connecting it to the connector; ▪ put the battery compartment cover in place again.

IMPORTANT!

4. PERFORMANCE OF CALIBRATION AND PROCESSING OF MEAUSREMENT RESULTS 4.1 Visual inspection

During such visual inspection the following shall be determined:

▪ compliance of the Analyzer set with the requirements of operational documents; ▪ absence of any mechanical defects that can affect the Analyzer serviceability and met-

rological characteristics;


46

▪ absence of defects that hinder reading of inscriptions and marking.

4.2 Try-out

The try-out is performed in order to test the functioning of the Analyzer. The Analyzer shall be switched on and tested in accordance with Operational Manual VYMP2.844.004OM. 4.3 Determination of Analyzer absolute error 4.3.1. Determination of absolute error when measuring moisture dew point. Connect the Analyzer to calibration unit. Not less than five points evenly distributed in the range from minus 30 °C to +30 °C shall be sequentially set in calibration unit in compliance with its operating documentation. It is possible to deviate from the range limit values by (5…10) ° C. It is recommended to set dew point temperature values in the following sequence: minus 25° С; minus 10° С; 0° С; +10 °С; +25° С. In order to determine the Analyzer absolute error when measuring the dew point that exceeds or equal to the ambient temperature, the Analyzer shall be placed into a thermal chamber the thermo-statting temperature in which is higher than the temperature being measured by not less than 5 °С to prevent condensation. After calibration unit starts operating under specified conditions and the Analyzer constant indica-tions are achieved, the three sequential dew point temperature values measured by the Analyzer and actual value of moisture in calibration unit are being recorded. Absolute error (ΔАi) is calculated by formula (1):

,gАiАiA −=Δ (1)

where: Ai – i-indication of the Analyzer,

Ag – actual value of dew point temperature in calibration unit.

4.3.2. Determination of absolute error when measuring hydrocarbons dew point The Analyzer absolute error is determined when measuring dew point of pure propane under fixed pressure. Manometer and valve B3 are connected to the Analyzer output union “OUTLET PORT” , propane cylinder with regulator and valve B1. Dry gas (nitrogen, air) cylinder with regulator and valve 2 are connected to input union «INLET PORT» via T-joint (see Fig. 1). Valve ”VENT.” shall be closed every time when measurements are carried out. Prior to measurements gas lines are tested for leaks. To do this close B1 and B3 valves. Then supply pressure of 1 MPa from the cylinder with pressed air (nitrogen) to DRY GAS output. Close B2 valve and read the manometer in 5 and 20 minutes. There shall be no pressure drop within 15 min-utes. After the Analyzer is tested for leaks it is supplied with power. Gas lines are dehumidified using dry gas prior to measuring propane dew point. Dehumidification level of measuring chamber is controlled in accordance with the Analyzer indications. Measuring chamber is considered dehumidified if moisture dew point being measured by the Analyzer does not exceed minus 25 °С. In order to remove technological gas or air traces from measuring chamber it is washed by propane.

IMPORTANT! Propane is combustible and shall be removed using suitable ventilation system.

.

The chamber shall be washed by propane not less than 6 times in the following sequence.


47

First propane is discharged into measurement chamber under pressure of 140 kPa, then B1 valve on propane cylinder regulator is closed and B3 output valve is opened, thus allowing propane to leave measurement chamber.

Figure 1– Diagram for connecting additional devices to Analyzer when measuring hydrocarbons

dew point

After the chamber is washed, B3 output valve is closed and measurement chamber is filled with propane. Pressure values corresponding to hydrocarbons dew points of minus 20° C, minus 10° and +10° C are set (see Appendix 1). It is possible to deviate from the given values by up to 5° C. B1 valve on propane regulator is left open in order to make pressure in measurement chamber constant during measurement cycle. After calibration unit starts operating under specified conditions and constant indications of the Analyzer are achieved, the three sequential dew point temperature values measured by the Analyzer and propane pressure value (by manometer) are recorded. Next basic absolute error at a given point is calculated by formula (1). Ag value is selected from Table 4. Table 3 Saturated propane vapors pressure (absolute) *)

Important!

Table 3 shows absolute pressure values. When calibrating analyzers according to i. 4.3.2 atmospheric pressure shall be measured and positive pressure values measured by manometer shall be correspondingly modified:

Р = Ризб + Ратм , Ризб – positive pressure measure by manometer, МPа; Ратм – atmospheric pressure measured by barometer, МPа.

4.3.3 Determination of calibrator absolute error during dew point reproduction. Mount calibrator connected to the Analyzer being calibrated on “CONG-Prima-4P” standard ana-lyzer (in case ”CONG-Prima-4” analyzer is used as a standard analyzer, calibrator shall be mounted between the Analyzer and sampling device). Measure dew point using standard analyzer (calibrator shall be disabled). In case measured value is lower than the dew point to be set, moisten calibrator mirror with distilled water. To do this remove calibrator from the Analyzer and apply distilled water on calibrator mirror using a brush. Mount calibrator on the Analyzer again. Repeat the measurement with disabled calibrator. Using calibrator sequentially set the three dew points and evenly distribute them in calibrator oper-ating range. It is allowed to deviate by 5-10°С from limit values of the range. The dew points being set shall be lower than values measured with disabled calibrator by 5 – 10°С. Using a standard analyzer, measure dew point at each value set by calibrator with preliminary time delay of not less than 30 minutes. Determine dew point reproduction absolute error (Δti ) in I-point of the range using formula 2: Δti = tзi- tиi, (2) where: tзi – set dew point in i-point of range, °С; tti – measured dew point in i-point of range, °С. 4.3.4 Calibration results are considered positive provided:

▪ dew point measurement absolute error does not exceed value specified in the Analyzer data card;

▪ absolute error of the dew point being reproduced by calibrator is within ±0,5 0С (onle for analyzers with calibrators).

4.3.5 Calibration results are considered negative in case the Analyzer being calibrated is not in compliance with the requirements given in section 4 of the present Manual.

5 PRESENTATION OF CALIBRATION RESULTS 5.1 Positive results of the Analyzer calibration are presented in compliance with ПоПР50.2.006 by issuing Calibration Certificate of the established form. When the Analyzer is calibrated without a calibrator, “without calibrator” shall be noted in Calibration Certificate. 5.2 The Analyzer that fails to pass the calibration procedure is not approved for use, its Calibration Certificate becomes invalid and the notification of its unfitness is issued. 5.3 Results of periodic calibration of analyzers delivered to Ukraine are presented in compliance with DSTU 2708–99. 5.4 Data on calibration procedures shall be entered into the Analyzer data card.

Averaged dew point values measured by the Analyzer are placed in the first column. Moisture values set using a calibrator (calibration means) are placed in the second column:

▪ enter the same values as in the second column “Calibrated” to the first column “Measured”;

▪ determine the Analyzer absolute error in accordance with i. 4.3 of КРАУ2.844.004MP Calibration Manual;

▪ enter dew point values measured by the Analyzer to “Measured” column, and set val-ues – to “Calibrated” column;

▪ if some of the values in “Calibrated” column are not set, highlight these points and remove them by pressing “Delete” button;

▪ if the set values are not found in “Calibrated” column, specify additional points using “Add” button and enter results of the measurement in these points to the table.

Important!

When performing hydrocarbons calibration of Analyzer “Hydrocarbons calibration mode” shall be enabled by selecting “CH calibration mode” submenu item in “Hygrometer” menu item.

2.1.7 “Log” subsection. Comments field with service information necessary to adjust the Analyzer is over the measurement process visualization chart. “Log” item of “Hygrometer” menu section is used for quick transfer to the comments field with service information. 2.1.8 “Restart” subsection. This item allows to restart the Analyzer measurement algorithm. However, indication of previously obtained values is kept. 2.1.9 “СН calibration mode” subsection. When this menu item is ticked in this menu item line, the Analyzer starts measuring hydrocarbons dew point in the forced mode. This item is only used when conducting hydrocarbons check and calibration. When hydrocarbons calibration mode is enabled, moisture dew point temperature is not being measured, and DPT indicator keeps the last measured moisture dew point temperature. 2.1.10 “Cleaning mode” subsection. This item is to be used when cleaning DPT sensitive element during its maintenance. When you en-ter this item, DTP sensitive element temperature is kept at +550С. More details regarding this cleaning procedure can be found in i. 3.2.3 of “Analyzer maintenance” section. After you press “Cleaning mode” icon with your mouse left button again, the Analyzer goes back to its standard operating mode.

2.1.11 “Set clean transducer level” subsection. This menu item allows to reset the photo signal level against which you determine contamination level of the Analyzer sensitive element. After this menu item is activated, the below window is dis-played:

Number corresponding to maximum photo signal level (in ADC arbitrary units) of the transducer used in this Analyzer entered to the above window by the manufacturer. This value may change mostly due to the contamination of the sensitive element during the Analyzer operation. Is the transducer cleaning procedure does not help to restore its initial photo signal level, this menu sub-section allows to accept the transducer current photo signal level after cleaning as maximum. For this purpose enter photo signal level value (green line at the visualization chart) in ADC units (right scale of the visualization chart) when cleaning mode is enabled (see i. 2.1.10) and after clean-ing the transducer.

Important! Factory adjustments of clean transducer level can be changed only after consultations with experts of SPC “Vympel” and only in case transducer is contaminated for more than 50 % (that is not possible to be eliminated by its cleaning)

2.1.12 ”Reporter» subsection. This subsection is used to start data storage, transfer and processing program on the terminal com-puter.

3 DATA STORAGE, TRANSFER AND PROCESSING SYSTEMS 3.1 General description of reports creation program. Two programming modules – “Archive2” and “UniView” – are used to store, transfer and process data. “Archive2” module (responsible for data storage) is enabled automatically when the Analyzer software system is being started. “UniView” module is used for viewing data and for creating re-ports on the Analyzer operation. 3.2 To start reports creation program select “Reports creator” section in “Hygrometer” main menu item in the Analyzer data display mode (Fig.3). the below window will be displayed:

Figure 4 – Reports creation program control panel

3.3. Working with reports creation program 3.3.1 The reports creation program main control panel “UniView” is divided into two windows (Fig.4). The left part is a branching catalogue based on “analyzers” with their numbers. Each “analyzer”, in its turn, comprises the following data: “events” – contains protocol of interferences to operation of the Analyzer as a whole, “data export” – serves to create files which then can be imported at other computers. “device # ХХХ”- are certain analyzers with factory numbers (xxx) connected (at the present moment or earlier) to this computer. Now these items will be described in more detail. 3.3.2 “Events” item. After entering this item you will see a protocol of events during the Analyzer operation in its right part. In order to obtain data on any events place flags (ticks) in the left upper part next to “All events”, “Interferences”, “Malfunctions”, indicating the events you want to learn about. Then specify date and time for the period of data required in columns “From” and “To” and press “Call” button. The events report is tabulated. The date and time of the event accurate within one minute are given in “Time” column. Event identificator is shown in “Event” column. If the column is empty, the event is the result of the program operation; if there is a “!” mark, the event is the re-sult of operator’s interferences; if the column contains “x” mark, the event can result in the Ana-lyzer malfunction.


56

3.3.3 ”Data export” item is not used when working with the Analyzer of this modification. 3.3.4 “Device # ХХХ” item comprises data on operation of the particular Analyzer with ХХХ fac-tory number and contains a number of items.

3.3.5 “Events” section of ”Device” item. After this section is highlighted, the right part of the win-dow will appear as below:

Working in this section is similar to that described in i.3.2.2.

3.3.6 “Daily report” section of “Device” item allows to obtain reports for a specified period of time in accordance with the adjustments and dump them. To do this the client machine (remote computer) being operated should have “Microsoft Excel ‘ 98” (or higher) supplement installed.


57

The upper line indicates calendar days within which a report has to be obtained and the contract hour from which the day will begin. The report table comprises the following data:

▪ “Time” column – measurement date and time; ▪ “Water” column – average hourly moisture dew point temperature, оС; ▪ “СН” column – average hourly hydrocarbons dew point temperature, оС; ▪ “Т” column – average hourly gas temperature, оС (if a transducer is mounted); ▪ “Р” column – average hourly pipeline pressure, MPa (if a transducer is mounted); ▪ “Events” column – events (malfunctions and interferences if any). Empty box indi-

cates that there is no any measurement at all or it is incorrect. When there are flags (ticks) in “Chart” window or “Detailed chart” window, data are being dis-played in graphical mode. To obtain data press “Call” button, and to print out the obtained data – press “Print” button.

3.3.7 “Monthly report” section of “Device” item. Operations in this section are practically the same as in “Daily report”. You should only enter a contract day in the respective window in addition to a contract hour and use average daily values in-stead of average hourly ones in this section. 3.3.8. ”Research report” section of ”Device” item. This section is used to obtain additional service information on the instrument operation within an optional period of time. This information is not necessary when operating the Analyzer.


58

When you place a flag (point) in the upper part of the right window next to “Measurement”, meas-ured parameters values are being displayed in the table at the bottom of the window. When you place a flag next to “Log”, text comments to measurement processes are being displayed in the ta-ble. These comments and the time of their occurrence are being displayed in the comments field (see Fig. 3) during the Analyzer operation. The time required to obtain data on measurement results is specified in “Period” window in “From” and “To” columns. The contract day and hour (i.e. the day and hour from which a conventional month will start and end, and days for month and daily re-ports, respectively) are specified in “Contract” window. In “Averaging” window a flag (point) is placed next to the inscription that corresponds to the required averaging type to be applied to meas-urement results. In case “Without averaging” is selected, parameter instantaneous values of meas-urement results will be present in the report. Selection between average hourly, average daily or in-stantaneous values of measurement results is made using flags (points) placed in “Report type” window. You may specify the type of data representation in “Report type” window. If you place a flag in “Day” or “Month” line, the report will be similar to that described in i. 3.2.6 or i. 3.2.7, re-spectively. In case you place a flag next to “Not specified” any period of time can be selected. If a flag is placed in “Now” line, it will be impossible to change the report end time, and the report will end by the current time. If a flag (tick) is placed next to “One period”, the report start time will be automatically counted for a specified period (“Day” or “Month”) back to current time.
