Calibration
Calibration
Calibration (or tank calibration) of the fuel tank in the Wiafleet system is the process of creating a correspondence table between the signal level from the fuel level sensor (FLS) and the actual volume of fuel in the tank. This is necessary for accurate fuel consumption measurement and to avoid errors in monitoring data.
1. Preparation
Before starting, make sure that:
-
A fuel level sensor (FLS) is installed and connected to the vehicle;
-
The device is transmitting data from the FLS to the system;
-
The tank is empty or nearly empty (recommended for starting the process).
2. Physical Fuel Filling (Data Recording)
The calibration process is carried out on-site:
-
Completely empty the tank (if possible)..
-
Fill the tank with small portions of fuel (usually 10 or 20 liters at a time).
-
After each refill, record the value transmitted by the FLS (voltage or frequency, depending on the sensor type).
-
Continue filling and recording data until the tank is full.
As a result, you will have a table:
X — the voltage value transmitted by the fuel level sensor (FLS) to the terminal at a specific amount of fuel in the tank
Y — the actual volume of fuel added to the tank at the moment the signal is recorded.
Eventually, you will get a calibration table that can be entered into the monitoring system in the settings of the fuel level sensor. This ensures more accurate fuel level representation in the system.
Tips
The more data points in the calibration table, the higher the accuracy.
Recalibration is necessary after replacing the FLS or changing the shape or volume of the tank.
