SOLUTION

Fuel consumption monitoring system of autonomous hybrid plants is based on differential fuel flow meter DFM and online
telematics unit.

Differential fuel flow meter DFM is mounted into fuel system and measures actual fuel consumption. Its installation doesn't
influence fuel flow in the system. The flow meter records operation time of engine in various operation modes and also registers
interferences into system.

Fuel consumption in different operation modes DFM 250D fuel flow meter

Data from the flow meter (instant and total fuel consumption, engine operation time and fuel consumption in idle, optimal and
overload modes, fuel temperature) is sent to online telematics unit via RS-485 digital interface. Information from telematics unit is
send to dispatch service computer in real time. Data on fuel consumption and engine operation time is available in reports and
diagrams.
