DFM Marine is installed in fuel line of the engine / boiler / burner, directly measures fuel consumption and generates an output signal, which is sent to telematics unit (GPS tracker).
DFM Marine is used in telematics systems (GPS tracking systems) and as an autonomous fuel monitoring solution.
Measuring chamber is made of corrosion-proof and highly durable material – brass.
Body and fuel line connections of DFM Marine can be made of duralumin (lighweight and inexpensive) or brass (corrosion-proof and more durable). Fuel line connection types – thread or flange – specified in purchase order.
Any two units of DFM Marine are configured from PC to operate in paired mode, without a need of selecting and calibrating two compatible pieces. Differential fuel consumption measurement mode is used for measuring consumption of fuel in supply and return fuel lines of an engine, if necessary.
