MEASUREMENT OF FLOW AND HEAT TRANSFERRED BY WATER STEAM Evaluation unit of the meter of heat in the systems of steam measurement INMAT 57 is designed, pursuant to Act No. 505/1990 Coll., as amended, for measurement of heat in the systems of measurement of water steam pursuant to MPM 18-95. Pursuant to Annex to the Decree No. 345/2002 Coll., as amended, as evaluation unit, which is a part of the heat meter. Furthermore, it can be used as meter of flown quantity of the condensate in the systems for steam measurement pursuant to MPM 18-95. The meter INMAT 57 enables: - Measurement of heat transferred by water steam with

direct method (without measurement of the condensate) in combination with the substitute method

- Measurement of heat transferred by water steam with indirect method, i.e. with a calculation from the quantity of overheated water steam detected by the measurement of quantity of the condensate and temperature and pressure of overheated steam, in combination with the substitute method

- Measurement of heat in condensate Flow of water steam is measured with throttling units or speed probes with one pressure difference sensor with output current unified signal or volume flow meter (e.g. whirl) with linear output signal of frequency or unified current. Flow of the condensate (for indirect method) is measured with volume flow meter (e.g. whirl) with linear output signal of frequency or with water meter with impulse output signal. Temperature of water steam in the piping is measured with a resistance temperature sensor with measuring resistor in four-

wire connection or with a thermometer with converter to the unified current signal. Operating temperature of water steam in the transferring piping may be 600 °C as a maximum. Temperature of the condensate (for indirect method) is measured with resistance temperature sensor with measuring resistor in four-wire connection or thermometer with converter to the unified current signal. Operating temperature of the condensate may be 200°C as a maximum. Pressure of water steam is measured with the absolute pressure sensor or with the overpressure sensor with unified current signal. The use of the absolute pressure sensor is recommended for the operating pressures smaller than 1 MPa. The meter INMAT 57 performs automatic correction of changes of density and enthalpy pursuant to IAPWS IF97 within the range of temperature from the limit of saturation to 600 °C and within the range of abs. pressure from 60 kPa to 18 MPa. The status of wet steam is signalled with the system of self-diagnostics. In case of a drop of the steam temperature under the limit of saturation, the measurement of flow and heat is switched over to the substitute method. The evaluation of flow and heat with both methods does not influence one another. Heat, heat output, flown quantity and flow steam within the zone of overheated steam are displayed on independent meters. The evaluation within the limited area of wet steam under the limit of saturation takes place on independent meters within the zone, the upper limit of which is the temperature of steam saturation (TS), the bottom limit is limited to 10°C under the temperature of saturation (TS - 10°C). Quantities of flow and thermal output in the area of wet steam are marked with the index mp. Heat and flown quantity under the limit of saturation are assessed separately in two zones. 1st zone within the temperature interval TS to TS - 2°C is marked with index mp, 2nd zone within the temperature interval TS - 2°C to TS - 10°C is marked with index mv. Data of the thermal output and heat in wet steam are multiplied with a coefficient Kh (0.5 to 1). In case of the direct method, data of flow and flown quantity in wet steam are multiplied with a coefficient Km (0.5 to 1). User adjustable coefficients Kh and Km are established contractually between the supplier and the customer of heat (implicitly Kh = Km = 1) and their change can be protected with a password. The measurement methods are established in compliance with MPM 18-95 (Directive for permissible methods of measurement of heat in water steam and in condensate in business contact). The limit of saturation is established pursuant to “International formulation of thermodynamic properties of water and water steam for industrial purposes IAPWS-IF97. Measurement in the area of overheated steam and measurement of the condensate has a nature of a rated operating meter. Measurement in the area of wet steam (so-called substitute method) has a nature of a non-rated operating meter. For billing purposes, it is necessary to use a measuring path for the measurement of flow that corresponds to the applicable standards or technical conditions of the used flow meter. The sensor pressure, thermometers and meters of the flown quantity of carrying medium, which are, together with the evaluation unit, elements of heat meters, shall be compatible with the evaluation unit INMAT 57, have type approval in the Czech Republic and have valid certification. MEASUREMENT OF HEAT TRANSFERRED BY WATER, MEASUREMENT OF COLD The meter INMAT 57 evaluates flow of water and quantity of heat transferred by water or it evaluates quantity of cold. The flow is measured with throttling units or speed probes with one pressure difference sensor with output current unified signal, volume flow meter (e.g. inductive, ultrasonic or whirl), mass flow meter with linear output signal of frequency or unified current and water meter with impulse signal. Temperature of the medium in transferring and return piping is measured with pair resistance temperature sensors with measuring resistor in four-wire connection. INMAT 57 can be used for a discretionary operating temperature difference from 0 to 200 °C and for water temperature from 0 to 200 °C. For measurement of cold, the temperature range is from -50 to 200°C. After an agreement, at a special request also in another smaller range.

Pressure of the medium for the calculation of flow is considered constant 1.6 MPa abs. Pressure can be measured and displayed for other purposes. In that case, pressure is measured with the absolute or relative pressure sensor with unified current signal. Measurement of pressure is only possible in connection with the frequency or impulse signal of flow. Bi-directional flow In connection with the bi-directional flow meter, INMAT 57 can evaluate both directions of flow of the medium. In case of use of the bi-directional flow meter, the signal of direction of flow of the evaluation switches over between the first circuit and the second circuit. If the signal of flow is of the current type, the direction of flow is switched over with the logical signal brought to impulse / frequency input (as contact or open collector). Signal connected for direction 1, disconnected for direction 2. If the signal of flow is of impulse/frequency nature, the direction of flow is switched over with unified current signal brought to input I3. Signal over 12mA = direction 1, signal up to 12 mA for direction 2. MEASUREMENT OF FLOW OF FLUIDS Flow of water and technical fluids is measured with throttling units or speed probes with one sensor of pressure difference with output current unified signal, volume flow meter (e.g. inductive, ultrasonic or whirl), mass flow meter with linear output signal of frequency or unified current and water meter with impulse signal. Temperature of the medium in the piping is measured with resistance temperature sensor with measuring resistor in four-wire connection or resistance thermometer with converter to unified current signal. The meter INMAT 57 can be used for water temperature from 0 to 200 °C and temperature of technical fluids from -50 to 200°C (maximum -100 to 600 °C). Pressure of the medium in the piping for the calculation of flow can be considered constant or measured with the absolute pressure sensor or the overpressure sensor with unified current signal. If constant pressure of the medium is considered, the measured pressure can only be displayed for other purposes. Bi-directional flow In connection with the bi-directional flow meter, INMAT 57 can evaluate both directions of flow of the medium. In case of using the bi-directional flow meter, of signal of direction of flow of evaluation switches over between the first circuit and the second circuit. If the signal of flow is of the current type, direction of flow is switched over with the logical signal brought to impulse/frequency input (as contact or open collector). Signal connected for direction 1, disconnected for direction 2. If the signal of flow is of impulse/frequency nature, the direction of flow is switched over with the unified current signal brought to input I3. Signal over 12mA = direction 1, signal up to 12 mA for direction 2. MEASUREMENT OF FLOW OF GASES - Evaluation unit of the meter of flown quantity of gas The meter INMAT 57 operates as an evaluation unit of flow and flown quantity of gases. Flow and volume of gas are recalculated to reference conditions of pressure and temperature, or, as the case may be, to mass. The unit consists of INMAT 57, measuring pressure converter (absolute pressure or overpressure) and measuring temperature converter. The evaluation unit is used in connection with the meter of flown volume of gas or, as the case may be, flow of gas. For billing measurement, it is necessary to use measuring converters with valid type approval and official certification identified in the Decision about gauge type approval. Measuring converters located on gas conduit with the use for heating, explosive and flammable gases shall have an approval for that particular environment. To ensure intrinsic safety of input and output signals of the evaluation unit, it is possible to use barriers approved for that particular environment. Flow is measured: - with throttling units or speed probes with one sensor of

pressure difference with output current unified signal


3 / 34

- volume flow meter (e.g. whirl) with linear output signal of frequency, impulse or unified current

- mass flow meter with linear output signal of frequency, impulse or unified current

- gas meter with output signal of impulse, frequency or with unified current

Temperature of gas is measured with resistance temperature sensor with measuring resistor in four-wire connection or thermometer with converter to unified current signal. Pressure of gas is measured with the absolute pressure sensor or the overpressure sensor with unified current signal. For heating gases, the sensor of relative pressure can be used only in case if the lower limit of the operating range of gas pressure is higher than or equal to 2.1 MPa abs. The temperature range is: - for heating gases from - 20 °C to 50 °C - for technical gases from - 50 °C to 100 °C - (other limits after an agreement with the manufacturer

maximum - 100 °C to 600 °C) Pressure range of the re-calculator is 5 to 100 % of the measuring range of the used pressure converter. The calculation of the correction or re-calculation coefficient of density considers the coefficient of compressibility. Compressibility can be constant or variable. The calculation of compressibility factors is realized for heating gases pursuant to AGA NX 19mod. or SGERG 88. For technical gases, the re-calculation of compressibility factors is realized by means of virial development or state equation (Van Der Waals, Redlich Kwong, Soave Redlich Kwong, Peng Robinson, Peng Robinson Gasem) according to an agreement with the user. INMAT 57 can re-calculate volume and volume flow for a discretionary relative conditions, e.g. to normal conditions (pn = 101.325 kPa, Tn = 288.15 K or pn = 98.0665 kPa, Tn = 293.15 K). Furthermore, it can evaluate mass and volume non-recalculated flow. INMAT 57 is not designed for operation in the explosive environment. Measuring converters in non-explosive design with fixed closure or in spark safe design can be used in the explosive environment, qualification of the environment pursuant to the used sensors. Any changes of the parameters and constants related to the calculation programme and applicable meters are protected with an official mark. Permitted changes of the parameters (depending on design of dv, %CO2, %N2, %H2, Hs, Vc, Pc, Tc and ) are efficiently protected with passwords and recording to memory that cannot be deleted. Description of the function of passwords and use of the metrological password is described in the article OPERATION AND MAINTENANCE, USER AND METROLOGICAL PASSWORD.

D E S C R I P T I O N INMAT 57 is located in the compact plastic box covered with the tilting lid with the display unit and two controlling push-buttons. After tilting the lid away, a sealable cartridge of the changer is accessible, which determines all metrological parameters of the device. The cartridge is provided with a connector terminal board that can be divided. The structural design enables a simple installation and uninstallation of partial components of this unit. The box of the evaluation unit is adapted for the installation on the wall and it enables a simple replacement of partial components of the unit. Controlling of the device is possible without opening the lid. The wires to the terminal board are brought with sealed outlets. The installation seal prevents from access to the terminal board. Seals on the cover of the cartridge of the meter prevent from access to the electronics (calibration seal or, as the case may be, an official mark for a certified design), which disable influencing the measurement with an unprofessional or intentional intervention. It is also possible to certify the actual cartridge of the meter without the display unit. Therefore, it is not necessary to disconnect cabling and remove the device from the wall. The official mark (self-sealing sticker located on the measuring cartridge) is visible through the through-hole in the face label of the device.

P R I N C I P L E The activity of the device is controlled with a one-chip micro-processor. Analogue input signals are transferred to the digital form with A/D converter and, with a possible impulse/ frequency input, they are processed in the processor. On the basis of such data, INMAT 57 calculates instantaneous mass flow, flown quantity etc. The calculated quantities can be displayed on the two-line 16-position alpha-numerical display from liquid crystals with back light. The selection of the required data for displaying on the display is made with the push-button MODE. Quantities displayed on the display are updated cyclically (with user-adjustable period). At the same time, it is evaluated if the quantities are within the pre-programmed limits. The second line of the display is used for displaying error messages as response to exceeding limits of some quantities and other internal tests. The assessed quantities can be transmitted by means of the interface RS485 or RS232C or M-Bus to the master computer. The network interface RS485 and M-Bus enable the meter to operate in the local network. On the interface RS485, it is possible to connect to 30 equipments (e.g. meter INMAT 57, INMAT 51, INMAT 66, ...) with one computer. On the network, it is possible to transfer all values stored in the unit. Communication network possibilities of the interface enable access to individual quantities of the devices, without violating the activity of measurement. By means of the communication interface, it is possible to set-up real time, date, user constants, menu user, conduct of error messages etc. The assessed quantities can be transferred to the following equipment in the form of a unified current signal 4 to 20 mA or impulse output signal. The selection of the output quantities and the range is adjustable by the user by means of communication interface and programme SWK45702. The provision of the analogue current output or impulse output is specified in the number of design refer to TABLE 1 - DESIGN OF METERS INMAT 57 - TYPE 457.

C O M M I S S I O N I N G After the connection, the device is prepared for operation. If the communication line RS485 is used, one device is configured as the end device by the change of the setup of switchovers of the terminating resistor. The device is delivered in the configuration of the transient member of the network (switchovers in position 0, terminating resistors not connected). These switchovers are accessible after tilting the lid of the terminal board away. If required, it is possible to set-up the date and time by means of communication interface. Note: Setup of time simultaneously for the whole group of the devices with the same password is possible by means of broadcast (group) address. A detailed description of the set-up is a part of the communication programme HELP. Before the start of the operation, it is necessary to comply with the period of heating of 30 min. INMAT 57 in the open design shall be provided, after commissioning, by an appointed worker of the installation and service organization, with marks of the installation and service organization. The installation seal (mark) secures the sealing screws on the right side of the device (refer to FIGURE 1 – DIMENSIONAL DRAWING).

O P E R A T I O N A N D M A I N T E N A N C E INMAT 57 is equipped with a two-line display for displaying the measured and calculated values, warning messages and data about the configuration. The measured values are displayed in the top line of the alphanumerical display including the units and the relevant text in the bottom line of the display. The texts are displayed including diacritics. To display the warning messages, the bottom line of the display is used. If more conditions were met for displaying an error message during the operation, warning messages are ordered into a list of warning messages, which can be scrolled in the menu Diagnostics. The display can display either only the sign of the error (flashing bell) or the most actual warning messages in the form of a running text. Actions of the diagnostics can be set-up in the menu Setup/Diagnostics or by means of SWK45702. Operation of the device is realized by means of two control push-buttons of the keyboard according to FIGURE 1 – DIMENSIONAL DRAWING. As a default, INMAT 57 is delivered in multi-language design. The user can select the language: Czech, Slovak, Polish, German, English and Russian. The language is set-up by the user directly on the device in the menu Setup/Language or by means of SWK45702. INMAT 57 is equipped with the user menu - User. In this menu, the user can set-up displayed quantities and their sequence. It is possible to choose from all data from the menu Operation. A big advantage of the menu User is that during the common operation of the device, it is possible to see only several key data and it is not necessary to scroll in an extensive menu Operation. The set-up is possible directly from the meter in the menu Setup/PořVmenuUŽIVAT or by means of SWK45702.

SETUP BY MEANS OF CONTROL KEYS The set-up of the parameters is realized from menu SETUP. You can switch to the menu SETUP with the push-button ACK from the MAIN MENU, from position >Menu SETUP with the push-button ACK. Another pressing of ACK returns you back, the push-button MODE moves to individual positions of menu SETUP. The set-up can be protected with a password. This status is signalled on the display with the symbol of a key. In this case, the device requests entering a valid password at first. Without entering it, it is not possible to change or see the adjusted parameters. With the push-button ACK, you can return to the Main menu, with the push-button MODE the device requests entering a valid password, which is signalled with flashing cursor under the first position of the password. With the push-button MODE, you can cyclically change the value (0 to 9). The push-button ACK moves to other position of the entered password, where you can change the value again with the push-button MODE. After correct entering of the fourth position of the password with the push-button ACK, INMAT switches over to the set-up mode. If the password is entered incorrectly, the text "Password is incorrect! Wait ..." is displayed and after approx. 5 sec the device is returned to the Main menu. ENTRY AND SETUP OF THE PASSWORD SETUP/New password - By pressing the push-button ACK, the device switches over to the mode of entering the user password. Another pressing of the push-button ACK returns you back to the menu SETUP, the push-button MODE switches over to entering the first position of the password. With the push-button MODE, it is possible to cyclically change the value (0 to 9).

BATTERY - SETUP/ > Battery By pressing the push-button ACK, the device switches over to the mode of measurement of the battery voltage. Another pressing of the push-button ACK returns you back to the menu SETUP, the push-button MODE switches over to the mode of measurement. On the display, the valid value of voltage of the battery and its status (OK for good and KO for discharged battery) is displayed within three seconds. On the first line of the display, the temperature TBAT is displayed (inside the box of the device) and the period of temperature of compensation of the real time clock, which can be adjusted to 64, 128, 256 or 512s. Implicitly the value 512s is set-up. A shorter period means more frequent compensation at the expense of shortening service life of the battery. A double pressing of ACK returns you back to the menu SETUP.

Warning! Voltage of the battery is checked after the start-up of the device and once per day at 24:00. Possible poor condition of the battery is indicated by the diagnostic system. The battery is also changed during the follow-up certification. PUSH-BUTTONS Push-button MODE This push-button enables a gradual selection of display of the values of individual quantities from the selected menu. After pressing the push-button, the following data is displayed automatically. The push-button is provided with the function auto-repeat. i.e. when it is pressed, the displayed quantities are selected automatically. The measurement and other functions are not impacted by the activation of the push-button MODE. In the menu SETUP, the push-button MODE is used for the change of the set-up item. Push-button ACK The push-button ACK has several functions according to the mode, in which the device operates. The main function is back scrolling in the items of the menu. The second function is switching over between individual menus. Another function is switching over of individual set-up items in the menu SETUP (e.g. at the set-up of the password). Key shortcuts: - Long pressing of the push-button ACK will return you from

anywhere to the MAIN MENU to the place for switching over to the menu USER.

- By pressing the push-button ACK, following long pressing of the push-button MODE and holding both, you switch over to the menu DIAGNOSTICS. Then you need to release the push-button ACK and then MODE.

DESCRIPTION OF THE STRUCTURE OF DISPLAYED DATA The displayed data is divided into several groups - MAIN MENU, OPERATION, USER, BALANCE, DIAGNOSTICS, SETUP, CONFIG AND SERVICE. Switching over between individual groups of data is realized as follows:

1) By means of the push-button MODE, we can select the text for switching over in the first line of the display

(e.g. OPERATION -> service). The current mode is displayed in capital letters, while small letters indicate the mode, to which you can switch over.

2) By pressing the push-button ACK (refer to help on the second line of the display), we select a new mode. The text is changed to the opposite one (SERVICE -> operation)

3) With the push-button MODE, we can now select the displayed data from the selected menu.

MAIN MENU The main menu is used for switching over between individual modes: USER, OPERATION, BALANCE, DIAGNOSTICS, SETUP, CONFIG AND SERVICE – refer to FIGURE 5 - STRUCTURE OF MAIN MENU. OPERATION In the menu OPERATION, virtually all assessed quantities are displayed, including time data and user-adjustable string, where the user can set-up e.g. the name of the measured circuit etc. - refer to FIGURE 6 - STRUCTURE OF MENU OPERATION. USER In the menu USER, the selected items are displayed from the menu OPERATION - refer to FIGURE 7 - STRUCTURE OF MENU USER. The user can set-up not only what items will be displayed but also their sequence. The selection and set-up is possible from the menu SETUP or from the computer by means of the service programme SWK45702. BALANCE In this menu, flown quantity and energy for the last hours, days, month and years are displayed. Structure of the data is in FIGURE 8 - STRUCTURE OF MENU BALANCE. You will exit the menu with a long pressing of the push-button ACK. DIAGNOSTICS This menu displays error messages, i.e. their number and for messages also the time of occurrence of the error and text of the error message, refer to FIGURE 9 - STRUCTURE OF MENU DIAGNOSTICS. Individual errors can be confirmed in this menu and deleted by pressing the push-button ACK. The symbol of the bell in the place between the date and time, which means a sign of an error, disappears. If the error still continues, the symbol of the bell and the current time appear again. SETUP In this menu, you can set-up a new password, date and time, automatic switching over of summer and winter times, parameters of the communication interface, select language of the device, set-up dimming of the back light of the display, contrast of the display and speed of refreshing of the data on the display, set-up items in the menu USER, action of the diagnostic messages, display the status of the battery and reset the maxima. Changes of the setup can be protected with a password. The active user password is signalled in the menu SETUP with a symbol of the key. STRUCTURE OF MENU SETUP without the password is in FIGURE 10, with the password in FIGURE 11. CONFIG The configuration data include the data about the type number and manufacturing number of the device, version of calculations, version of the firmware. This menu also displays the type of application, calculated parameters, ranges of input and output signals, their meaning etc. Structure of the data is in FIGURE 12. Note: In the mode CONFIG, on the second line of the display, only a sign of the possible error detected by the diagnostics is displayed. The running description of the error is not displayed. Possible warning message appears after switching over to another mode (USER, OPERATION, SERVICE). If the operator leaves the device in the mode CONFIG, the device switches over after eight minutes to the mode USER to the 1st . item, which ensures displaying of warning messages. SERVICE In the menu SERVICE, parameters of communication interface are displayed (address, speed, parity); then it displays additional data, which are used for more detail information about the measured object (enthalpy and specific volume of the medium, temperature of saturation, ...) and values of input signals. For the STRUCTURE OF MENU SERVICE - refer to FIGURE 13 - STRUCTURE OF MENU SERVICE.

USER AND METROLOGICAL PASSWORDS The meter INMAT 57 is equipped with USER and METROLOGICAL passwords. These passwords block changes of some parameters (time and date, user constants ....). When entering any of the protected values, INMAT 57 requests entering a valid password. If the password is correct, it permits entry of the data to the device. The user password can be changed or blocked. For this change, it is necessary to know the current user password. The user password can be deactivated permanently by entering the value of the password "0000" (4 zeros). By entering another value, the function of the password is reset. The length of the password is 4 characters ['0' to '9'], and it can be changed in the menu Setup / User password or from the computer and programme swk45702. The password can be changed by entering the currently valid password at first; after its confirmation, enter the new password 2 × (with the confirmation). The second entry of the password is intended for inspection and if it does not match the first one, the new password is not set-up. INMAT 57 is delivered with the user password set-up to 0000, i.e. the password is switched off. The meter INMAT 57 in design for measurement of gas enables a change of its composition (according to design dv, %CO2, %N2, %H2, Hs, Vc, Pc, Tc, ). The change is realized by software by means of a computer connected to the communication interface. The change is possible in cases when compressibility is pursuant to AGA NX 19mod., SGERG 88 or virial development. The change of the parameters of gas is protected with the user and metrological passwords, without which such change is not possible. When entering any value to INMAT (composition of natural gas, time and date, address, user constants, parameters of archiving ...), INMAT 57 requests entry of the

valid password by means of a request on the computer. If the password is correct, it permits entry of the data to the device for the period of three minutes. After this period, the access is blocked and further entering of data to INMAT 57 requires a repeated entry of the valid password. When changing the parameters of gas, data are entered to the archive of changes. The following is stored to the archive of changes: date and time of change, new parameters and who made the change (user, metrologist or change without the password when the password is deactivated). The archive of changes can be read by means of interface RS485. By means of the user password, it is possible to realize 100 changes; when this number is exceeded, other changes can only be realized with the application of the metrological password. This password can release the archive of changes for the new set-up (again 100 changes). A detailed description of work with the password is included in Help of the service programme delivered by the manufacturer of the device. A forgotten password can only be unblocked at the manufacturer at the expense of a violation of the seals and loss of validity of the certification! MAINTENANCE Replacement of the internal battery (CR2032) is realized during the follow-up certification, or, as the case may be, at the latest after 5 years. If the internal battery is discharged sooner, it shall be replaced. Discharging of the internal battery is signalled by the diagnostics of the device. Status of the battery can be identified also in the menu SETUP/ BATTERY. During the replacement of the battery, the stored data remain without damage. If power supply is switched off during the replacement of the battery, it is necessary to set-up date and time in the device. OPERATION AND MAINTENANCE OF RATED METERS For rated meters, it is necessary to comply with the prescribed period for follow-up certification in the intervals identified by the
