Using J1939 output protocol makes possible DFM CAN operation as a part of
telematics bus together with DUT-E CAN fuel level sensors and other factory-built or
additional equipment (see figure 3 b). Tracking device with a single CAN interface port can
receive data from up to 8 DUT-E CAN sensors and up to 8 DFM CAN meters. This possibility
is especially useful while Vehicles with several engines (river boats, locomotives,
technological vehicles, diesel genset stations) are equipped.

based on the DFM CAN data
Use of DFM provides vehicle owners with the following:
 actual fuel consumption records;
 registration of machinery working time;
 normalizing of fuel consumption quotas;
 fuel theft detection and prevention;
 real-time monitoring and fuel consumption optimization;
 fuel consumption tests for engines.
