Applications

DFM Marine

DFM Marine is a precise tool for fuel consumption measurement of maritime transport, locomotives, high-power diesel generators, mining and quarrying machinery, boilers/burners. DFM Marine fuel flow meters can be used within Telematics systems as well as stand-alone autonomous solution. DFM Marine is installed in fuel system of engines/boiler/burner, measures instant fuel consumption per hour and sends outputs signal to vehicle tracking device.

Communication protocols

Implemented J1939 protocol allows DFM Marine CAN to be used within S6 Telematics interface together with DUT-E CAN fuel level sensor and other equipment. Telematics device can obtain data via just 1 CAN-port – from up to 8 units DFM Marine CAN and up to 8 units of DUT-E CAN. This option is useful when monitoring fuel of several engines simultaneously (vessels, locomotives, group of gensets, boiling equipment).

Materials

Measurement chamber of DFM Marine is made of corrosion-proof metal – brass. Body and thread/flange is made of either brass or duralumin.

What data you can get from flow meter DFM Marine

Each DFM Marine has a screen, that visualizes data on its measurements. Some models, apart from embedded electronic display also send data via its digital interface or pulse output to onboard telematics device or other data recording unit.
