Fuel Consumption sensor report

Hello

I have a connected to the tracker a sensor that reads control pulses from wires of engine injector and converts them into normalized pulses, which are sent to data processing unit. Number of sent pulses is directly proportional to the volume of consumed fuel.

The value comes as : Io136

To calculate the fuel consumption the manual tells me this:

Each output pulse of sensor corresponds to a certain volume of consumed fuel. Thus, the sensor pulse values are individual for each vehicle. To calculate the volume of consumed fuel, a calibration factor C is used in the telematics system. In order to define calibration factor C for the sensor the following procedure should be applied to each vehicle:

1. Set the initial value of the calibration factor C=300 imp/l at the terminal or server.
2. Fill the tank to the full.
3. Consume 20% of the fuel tank volume at a standard driving conditions of the
   vehicle.
4. Fill the tank to full (at the same petrol station)
5. Estimate the volume of consumed fuel according to the indications of the fuel pump
   dispenser (V).
6. Estimate the volume of consumed fuel according to the telematics system indications
   (W).
7. Calculate the calibration factor C using the following formula:

C = 300 - W
———-—— , impulses/liter
V
8) Set the calculated calibration factor C at the terminal or server.
