2.1 Marking of important information

Important information is specially highlighted in this user manual.

WARNING

To avoid danger to persons, this information is marked with WARNING.

CAUTION

To avoid danger to equipment, this information is marked with CAUTION.

NOTE

Special information for operation / commissioning and maintenance is marked with

NOTE.

2.2 General safety regulations

Before using the TrigasDM flow meter, this user manual and all safety instructions

must be carefully read in their entirety and understood.

Take all necessary precautions to ensure the safety of personnel and equipment.

These precautions include, but are NOT limited to, the following examples:

Mechanical and electrical installations must only be carried out by qualified and authorized personnel.

It must be ensured that the measuring range of the flow meter is not exceeded.

Do not install measuring instruments and cables in the vicinity of strong magnetic sources, such as electrical cables, electric motors, transformers, welding equipment, relays or high-voltage cables. These sources can cause electrical noise, resulting in incorrect pulse signals.

Flow meters, which are designed for applications in liquids are not suitable for applications in gas.

The valid safety standards (for example, in accordance with the German Occupational Safety and Health Act) must be observed for the installation and/or operation of the flow meter. Non-observance can result in DANGER to personnel.

A flow meter is a precision instrument. Do not use compressed air to clean the flow meter or check its function.

Lysis must be disconnected from the voltage source before changing the turbine with the SMART-Pickoff.



3. Description

3.1 Design and measuring principle Lysis is an intelligent and compact flow rate transmitter for linearizing flow meters and offers real-time compensation for viscosity, density and temperature. Moreover, it is compatible with any flow meter that is equipped with a Lysis "SMART-Pickoff".

Automatic sensor identification (plug & measure): SMART-Pickoff is a sensor that contains the calibration data of the flow meter. Every Lysis can be used with any flow measuring instrument. The assignment of the temperature to the viscosity is saved in the electronics depending on the medium. The temperature is measured by the measuring sensor (pickoff) and compensation of the density and viscosity is enabled in this manner. The output after scaling takes place both as an analogue signal 0-10 V (optionally 4-20mA) and also as a frequency signal 0-5100Hz with a calculation time of about 1.5 to 2.5ms.

The software that is easy to operate and work with permits programming and scaling.

Matching only with Low Profile SMART-Pickoff

WARNING:

Signal Output GND use separated from Power Supply GND / Pin2 ≠ Pin 5

It is recommended to use not more than 15m cable between Lysis and

SMART-Pickoff with no more than 1 extension cable.

4. Installation / commissioning

4.1 Safety regulations

Mechanical and electrical installations must only be carried out by qualified and authorized personnel.

When working on electrical systems, the 5 rules on safety from the DIN VDE 0105 series of standards should be applied diligently and carefully: - De-energize

- Secure against being switched on again

- Ensure absence of voltage

- Connect to earth and short-circuit

- Cover or fence off live adjacent parts

4.2 Checks after delivery

Carefully unpack the product and check for cleanliness (e.g. packaging residues).

Check its condition and check for damage.



4.3 Principle of operation

a. Impact of the viscosity A turbine flow meter changes its frequency output with a change in the viscosity. In

other words, the higher the viscosity, the lower is its output frequency with the same

flow rate.

A good display method for assessment is generally the ratio of the frequency to the

factor pulses/litre (pul/lit).

b. Compensation of the effect of viscosity

A turbine flow meter has the characteristic of behaving consistently in the linear

measurement range in the factor of frequency to viscosity.

This is represented graphically as follows.

You can clearly identify a deviation from the ideal line in the blue line

(=1.3 cSt or mm²/sec.). These calibration points of the turbine are not used for

subsequent linearization and temperature compensation.

c. Calculation method The electronics contains an assignment of the temperature to viscosity. This table is

provided to the customer for programming or he can program it himself.

This table must be equivalent to the current operating medium.

The current viscosity is determined continuously from the current temperature and

this table.

Determining the viscosity (Assignment °C to mm²/sec.)

Measurement of the current input frequency and calculation of the current factor (f/V = Frequency to viscosity)

Determining the current K factor (pul/lit) from the programmed table

Conversion of the K factor with the help of the current frequency in the current throughput (e.g. litres/min.)

Optional: Conversion of the throughput with the help of a programmed temperature/density table and the current temperature in a mass throughput (e.g. kg/min.)

Scaling and output of the current temperature at the analogue output (e.g. -50…+150°C = 0…10 volts)

Scaling and output of the current throughput at the analogue and frequency output. (e.g. 0…10 l/min. = 0…10 V = 0….2 kHz)



4.4 Programming the electronics

a. Tool necessary

Power supply 12-32 V DC

Computer with appropriate USB port and a Windows Operating System (We recommend Windows 7 or higher)

LPU software

Programming modem (sold separately) Possibly a voltmeter (Ammeter) for the new comparison of the analogue

outputs and functional test

b. Read-out from the electronics

Supplying the electronics with voltage, connecting the programming cable and opening the software.

"COM Port" tab and then choose an appropriate port from the list

Reading out from the electronics with the help of the "Read EE" button.

If the data is not read out correctly, the operation must be repeated.



c. Importing the calibration curve A Trigas calibration file "*.sav" is necessary for the programming

Choose the option "Load F/V kCurve" in the "File" menu – for temperature-compensated programming (Frequency/Viscosity vs. K-factor) / – Refer to Section 4.3.

Choose optional "Load F kCurve" – for non-temperature compensated programming (Frequency vs. K-factor).

After the data has been reloaded, the serial number must be compared with that of the calibrated flow meter.

Optional: Manual entry of the calibration curve is necessary only if the data is not available to you. NOTE The values must be entered with a dot as the decimal point separator. e.g. 15.45 instead of 15,46

d. Adjusting the electronics

Cut-off (ms) Maximum waiting time for completing a signal period. If this time gets exceeded, no input signal gets detected and all outputs are set to zero.

Update rate (ms) Measurement period before a measurement result is obtained and calculated. Special case: "0" means that the calculation is already taking place after one pulse.

Recommendation: Cut Off = 2 × Update Rate



Timebase (sec.) Time constant for conversion from the K-factor and flow units.

o 1 = xxx/sec. o 60 = xxx/min. o 3600 = xxx/hour

Minimum frequency (Hz) Lowest frequency (Leakage flow rate). Below the frequency, the TriLIN displays zero at all outputs.

Crystal factor Correction factor for internal time base.

Mode Operating mode of the electronics.

Mode Compensation Analog Output Frequency Output Memory

0 UVC Volumetric Volumetric Internal

1 none Volumetric Volumetric Internal

2 UVC Mass Volumetric Internal

3 none Mass Volumetric Internal

4 UVC Volumetric Mass Internal

11 none Mass Volumetric External

12 UVC Volumetric Mass External

13 none Volumetric Mass External

14 UVC Mass Mass External

15 none Mass Mass External

Mode 0-7 Data is stored in Lysis Internal EEPROM - any Pickoff may be used

Mode 8-15 “Smart Principles”

Data is stored in the SMART-Pickoff external EEPROM.

After exchanging the SMART-Pickoff, data are automatically reloaded.

The Pickoff should be fastened to the turbine.

Temperature offset

This allows the temperature to compensate for X°C.

e.g. measured temperature: 25°C

temperature offset: 2°C

temperature shown: 27°C



e. Liquid data changes The data pertaining to the media can be corrected whenever desired. To do this, choose the option "Load Fluid" in the "File" menu in order to load the new data. The table can also be edited manually as an option.

NOTE

The values must be entered with a dot as the decimal point separator. e.g. 15.45 instead of 15,46

If require, the fluid name can be changed.

e.g. "cooling water"

f. Scaling the outputs

Frequency output

You only assign the desired scaling in the fields. You can set the units with "Mode" and "Time Base".

e.g.: Mode – 8: Frequency output, volumetric

Time Base – 60 per minute Flow / Frequency



0-100 l/min. = 0-1000 Hz

Flow, analogue output

Mode – 8: Analogue output, volumetric Time Base – 60 per minute

0-100 l/min. = 0-10 V (possibly 4-20 mA) Volts (bits) – A/D value is calculated automatically

Temperature, analogue output

-50 – 150°C = 0-10 V (possibly 4-20 mA)

g. Programming To program the electronic press the program keys: 1. "Write Data to RAM" - Saves the data in RAM - after power failure this data will not be saved 2. "Write Data to Internal EE" - Saves the data in EEPROM Lysis 3. "Write Data to External EE" - Saves the data in EEPROM SMART-Pickoff

After successful programming has been completed, the message appears:

In Lysis always both EEPROM should be programmed.



It is advisable after programming:

a. Turn the supply voltage off for about 3 seconds and then turn it on again

b. Read and check data from RAM

c. When lysis has been programmed with "Smart Principles" (Mode 8-15), you can

exchange the SMART-Pickoff and re-reading the data.

- Unplug SMART-Pickoff

- wait 2sec.

- Insert a new SMART-Pickoff

- Read data

Run Live

After programming, the program enables the data to be checked. The Live mode is started by pressing the "Run Live" button.

h. Saving data Save the settings in the "File" menu option with "Save All" (*.lin)

The saved "* .lin" file may ONLY be reused with the programmed Lysis

& Pickoff.

The "* lin" file contain Hardware specific data. - Analog adjustment -

Therefore, these data may not be transferred to other Lysis devices,

otherwise there will be a change in the accuracy.

By a new programming it is recommended:

Do not use a "* .lin" file. Read the data directly from the Lysis, change and save it

again. Repeat the reading process on each device.

In the menu "File" is the possibility to load only fluid data (load fluid) and

to save (save fluid). This doesn’t change the calibration data.

If you need further information, please contact us.



i. Printing the data You need Excel 2010 or later to print the data. Open the Excel table enclosed.

Confirm the security warning with "Activate contents" Load the saved data with the "Load LIN" button. Enter the serial number of the electronics. Print out the report.



4.5 Adjusting the analogue outputs

NOTE The adjustment should be carried out only with a calibrated voltmeter or ammeter.

Connect the electronics as you do for programming with the data cable and

power supply.

Connect the voltmeter (or ammeter) to the analogue output to be calibrated.

Read out from the electronics with "Read EE".

There are arrow keys and scroll bars located to the right side of the scaling

fields with the help of which the bit values of the respective analogue outputs

can be changed.

With the upper scroll bar, you can set the minimum value on the multimeter

(e.g. 0 V for 0-10 V), and then with the lower scroll bar you can set the

maximum value (e.g. 10 V for 0-10 V). Press STOP at the end -> repeat this

for the second output.

To program the electronic press the keys: o „Write Data to RAM“ and

o „Write Data to Internal EE“



4.6 Trouble shooting

4.6.1 Electronic has no output signal

a. Check supply voltage (9-32V DC)

i. Standard current consumption is (depending on the configuration) up

to 40mA.

- Current > 100mA - board defective.

- Current = 0 mA - electronic connected incorrectly.

b. Flowmeter functionality check

i. Attention! The turbine should not be tested with compressed air -

turbine

may be damaged.

ii. Flow simulation: turbines pickoff evaluation – Remove pickoff from

the

turbine and move an iron element (not stainless steel) under the

pickoff

back and forth.

iii. Pickup Resistance Measuring - between pin 1 and 8

RF Sensor: 10Ω +/- 15%

c. Check the condition of the electronics (if available) connect electronics

with PC and RUN LIVE Switch Mode

→ Programming - Point 4.4

4.6.2 Baseline value appears to be wrong

a. If a problem is noted - RUN LIVE check mode. b. Compare Analog temperature output versus medium (liquid, gas) temperature.
