DFM Marine fuel flow meter

 

 

DFM Marine measures real fuel consumption and working time of engines, boilers/burners, defining fuel consumption in different operation modes.

— 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.

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

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).

 

 

Fuel consumption and working hours counters

 

 

DFM Marine fuel flow meters display counters on embedded electronic display and also send data via digital interface or pulse output to onboard telematics device or other data recording unit.

Information on embedded display of DFM Marine :

  • instant fuel consumption rate
  • total fuel consumption
  • total working time
  • working time in "Idling" mode
  • working time in "Optimal" mode
  • working time in "Overload" mode
  • additional resettable fuel consumption counter

 

Via digital interface DFM Marine sends:

  • instant and average fuel consumption rate
  • total fuel consumption
  • fuel consumption in "Idling" mode
  • fuel consumption in "Optimal" mode
  • fuel consumption in "Overload" mode
  • total working time
  • working time in "Idling" mode
  • working time in "Optimal" mode
  • working time in "Overload" mode
  • Events "Interference" and "Tampering"
  • Events "Ignition ON/OFF" and "High/low power supply"
  • additional resettable counters: fuel consumption and working time
