Digital flow meter DFM D

DFM D differential fuel flow meter is designed for diesel fuel consumption measurement in fuel lines of vehicles and stationary engines, and is used as part of GPS vehicle tracking system. In addition, DFM D registers working time of engine in various modes of operation. DFM D is used for consumption monitoring of: diesel fuel; heating oil; other types of liquid fuel with a kinematic viscosity of 1.5 to 6 mm2/ s. DFM D fuel flow meters, which re equipped with display, are used as a stand-alone (autonomous) solution for accounting fuel consumption, not requiring any connection to a web-server. DFM D are more suitable for modern engines (Common rail or pump injector fuel systems) of vehicles and stationary units. Differential measurement of fuel consumption DFM D has two measuring chambers for supply and return fuel lines. The flowmeter measures fuel consumption in each line and computes the difference between supply and return. The result is stored in an appropriate Counter. Values of Counters are sent to telematics (monitoring) unit as digital messages (for DFM with RS232, RS485 or CAN output). Built-in battery In case of absence of an external power source, for example, from the on-board network, DFM keeps on to register data to the internal memory. When external power is restored, all accumulated data will be transferred to the on-board monitoring terminal. Replaceable mud filter Installed in the inlet of DFM D. Protects flow meter supply chamber from particles of dirt and sand, which went through fine filter. The mud filter significantly increases reliability and durability of the flowmeter.
