3. Description

3.1 Design and measuring principle The TriLIN electronics amplifies, linearises and scales the frequency signals of almost all commercially available flow meters.

The offsetting and temperature compensation is done in accordance with a principle designed for turbine flow meters.

The output after scaling takes place both as an analogue signal 0-10 V (optionally 4-20mA) and also as a frequency signal 0-4800 Hz with a calculation time of about 1.5 to 2.5 milliseconds.

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

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-energise - 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 cable (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



• Time Base (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 this frequency, the TriLIN displays zero at all outputs.

• Crystal factor

Correction factor for internal time base.

• Temperature offset Additional compensation factor for temperature correction with normal use (should be 0 for normal use).

• Use Volts Input

0 – PT100 Input 1 – Analog Input (analog Temp.)

TriLIN can use for Temperature PT100, or Analog Signal. Signal is manual scalable. e.g. 0…10V = -20…120°C

Attention! To use this input please contact the manufacturer.

• Temperature offset Additional compensation factor for temperature correction with normal use (should be 0 for normal use).

• Mode

Operating mode of the electronics.

Mode Compensation Analogue output Frequency output 0 UVC Volumetric Volumetric 1 None Volumetric Volumetric 2 UVC Mass Volumetric 3 None Mass Volumetric 4 UVC Volumetric Mass 5 None Volumetric Mass 6 UVC Mass Mass 7 None Mass Mass



• Version Should not be changed.

• Pt100 K-factor (bits to Ohm)

K-factor of the PT100 input. Should be corrected only when determining deviations of temperature input.

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

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 – 0: Frequency output, volumetric

Time Base – 60 per minute Flow / Frequency

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



• Flow, analogue output

Mode – 0: 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 Press the "Write EE" button to program the electronics. After successful programming, the message appears:

Attention! The period of time after pressing the "Write ..." and the "Success" message should be 3sec. If not, the process should be performed again.



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) i. Help If you need further information, please contact us.



J. Printing 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.

• Press the "Write EE" button to program the electronics.



4.6 Adjusting the PT100 input NOTE You should carry out this adjustment only with a calibrated resistance decade

• Connect the electronics as you do for programming with the data cable and power supply. • Connect the decade at the temperature input and set 100 Ω. • Read out from the electronics with "Read EE" • Enter 100 in the calibration field and press the "Calculate" button – The PT100 K-factor is

recalculated.

• Press the "Write EE" button to program the electronics.
