DFM flow meter - accurate tool for direct fuel consumption measurement and engine operation time monitoring. DFM is used for detecting fuel theft from fuel line, rationing and optimizing consumption of fuel. Parameters and Counters: hourly fuel consumption rate; operation by fuel rate; fuel temperature; total fuel consumption and engine operation time; total fuel consumption and engine operation “Idle", “Optimal", "Overload", “Cheat", “Interference" operation mode ; total fuel consumption - feed and reverse chamber (differential fuel flow meter). Exceptional features: inbuilt battery - data recording without external power supply; configuration over Bluetooth - using smartphone and service adapted-inbuilt mud filter - additional protection of measuring chamber; Event recognition: • cheating (tampering) fuel consumption counter, • interference time into operation of flow meter's, • ignition on/off. Field of application: ■ GPS vehicle tracking and AVL systems; ■ industrial monitoring systems. Machinery: ■ tractors, harvesters and other agri- machinery; ■ bulldozers, graders and similar road-building machinery; ■ special machinery - rig drilling vehicles, steam generation vehicles, etc.; ■ railroad machines; ■ diesel gensets, boilers, burners.
