Step-by-step Dynamic Calibration Procedure
Step 1. Sensor Preparation
- Ensure the sensor is installed correctly.
- Complete all equipment preparation requirements specified in Section 2.
Step 2. Refuelings
- Obtain 1 to 4 refuelings from the customer.
- At least one refueling must be a full-tank refueling.
- All refuelings must have confirmed volumes.
Step 3. Data Collection from the FMS
For each refueling, determine:
- sensor value before refueling (N or voltage/frequency);
- sensor value after refueling (N or voltage/frequency);
- actual refueled fuel volume.
Step 4. Entering Data into the Omnicomm Calibratex
1. Select:
- sensor type;
- sensor calibration method;
- tank type.
2. Enter:
- initial and final sensor values;
- refueling volume.
For LLS AF 4 when the system operates with voltage/frequency values:
- specify the minimum and maximum U/F values configured in the sensor and GPS tracker;
- enter data in the same units as received from the FMS.
3. Add additional refuelings (if available).
4. Click Calculate.
5. Compare the service’s calculated refueling volume with the actual volume. In case of significant deviations, verify the correctness of the entered data and the selected tank shape. In some cases, actual refueling volume data may be incorrect due to inaccurate fuel station measurements or human error during data transmission. In such cases, it is necessary to verify the calibration table construction by excluding refuelings with the largest deviations.
6. Fill in the e-mail field and the calibration table name.
7. Click Send results by E-mail.
Step 5. Uploading the Calibration Table
- Download the received table from the e-mail and verify that the required file format (XML, CSV) has been generated correctly.
- Upload the table to the FMS (Omnicomm Online or another system).
