Calibration
Calibration of the fuel tank is necessary to verify the conformity of the digital code issued by the Omnicomm LLS 5 sensor to the fuel volume in a particular fuel tank.
Calibration of the fuel tank is performed by refueling up the tank – from empty to full, with a certain refueling interval, and recording the Omnicomm LLS 5 sensor readings in the cali-bration table.
A container may be calibrated by draining.
The calibration of a container with multiple Omnicomm LLS 5 sensors is performed simi-larly to the calibration with one sensor. Before the calibration process, add the necessary quantity of sensors and specify the network addresses.
The calibration is performed for all sensors simultaneously. Connecting multiple sen-sors to a PC using a KTZ splitter.
Calibration of the tank with one Omnicomm LLS 5 sensor:
1. Empty the fuel tank
2. Connect the sensor to a PC according to the diagram in the Setting section
3. Run the Omnicomm Configurator program. Select “Calibration”.
Omnicomm Configurator (PC):
If the sensor reading column is not displayed, press the “Add sensor” button. Select the type of sensor. Specify the network address set for the sensor during the setup.
4. Set the flow interval in liters
If the tank has irregular shape, and/or there are wider or narrower parts, it is recommended to perform calibration on such tanks with higher amounts of calibration steps to improve accuracy.
5. Press the “Start/continue calibration” button
6. Fill with an amount of fuel equal to the flow interval
Refuel using a measuring container or under control of a fluid flowmeter with the preset interval. The container must have the metrological calibration test certificate.
7. Press “Add line”
The “Liters” column will display the refueling volume equal to the predefined flow interval.
The “Sensor” column will display the value equal to the refueling volume.
8. Press “Add line”
9. Repeat items 6, 7 and 8 according to the number of control points. Minimum recommended number of control points: 20. Use the “F2” key to export a calibration table with more than 65534 liters of fuel volume.
10. Press the “Finish calibration” button
11. Save the calibration table in a calibration file (.ctb), Omnicomm Online (.xml) file, in the Terminal or in the Indicator, by pressing the “Export” button
When performing the calibration table export to the Omnicomm Online (.xml) file, the “Export” window will open. Specify the Omnicomm LLS sensor number to display in Omnicomm Online.
