13.2. FUEL CONSUMPTION MONITORING

The unit is capable to display the actual fuel consumption of the engine by two different ways:
▪
Through J1939 fuel consumption information
▪
By counting fuel consumption pulses.
If the engine is sending the fuel rate through J1939 messaging, then the unit will directly display the fuel
consumption information coming from the ECU.
If a flowmeter is installed at the fuel suction hose of the engine, then the unit is also capable of counting
these pulses, calculating and displaying the fuel consumption.
