Purpose DFM flow meter - accurate tool for direct fuel consumption measurement and operation time monitoring of diesel engines, diesel generators, oil boilers and burners. Goals: monitoring of real fuel consumption; preventing fuel theft ; fuel consumption optimization; machine hours accounting. hourly fuel consumption rate; operation by fuel rate; fuel temperature; total fuel consumption and engine operation time; fuel consumption in "Idle", "Optimal", "Overload" modes; total fuel consumption - feed and reverse chamber (differential flow meter). engine operation time in "Idle", "Optimal", "Overload" modes; fuel consumption and operation time in "Tampering" mode; operation time in "Interference" mode. Exceptional features: inbuilt battery - data recording without external power supply; configuration over Bluetooth; inbuilt mud filter - additional protection of measuring chamber; Event recognition: • cheating (tampering) fuel consumption counter, • interference time into operation of flow meter's, • high/low level of supply voltage, • ignition on/off. thermal correction feature. Field of application: ■ GPS vehicle tracking; ■ industrial monitoring systems; ■ engine fuel system diagnostics; ■ "predictive maintenance" - technical maintenance according to condition of engine and fuel system. ■ tractors, harvesters and other agri- machinery; ■ bulldozers, graders and similar road-building machinery; ■ special machinery - rig drilling vehicles, steam generation vehicles, etc.; ■ diesel gensets, boilers, burners. Electronic interface: * HP- high performance version, increased MAX fuel rate FUEL MONITORING EXPERT
