Technoton DFM-D Differential Fuel Flow Meter

Technoton DFM-D Differential Fuel Flow Meter 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 a GPS vehicle tracking system.

Technoton DFM-D Differential Fuel Flow Meter 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 a GPS vehicle tracking system. In addition, DFM D registers the working time of the 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 are equipped with a display, are used as a stand-alone (autonomous) solution for accounting fuel consumption, not requiring any connection to a web server. DFM D is more suitable for modern engines (Common rail or pump injector fuel systems) of vehicles and stationary units.
