Technoton DFM Differential Fuel Flow Meter

Technoton DFM 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.

Technoton DFM 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.

Features

• conformity with European and national automotive standards and
directives;
• protected from unauthorized tampering and “cheating”*;
• engine working time tracking separately for different operation modes;
• maximum information richness of output data**;
• high reliability of data transmission over digital interfaces **;
• unique self-diagnostics feature to monitor the stability and accuracy of
data**;
• possibility of integration into on-board telematics bus of vehicles ***;
• built-in mud filter;
• minimum fluid flow resistance;
• 100 % of DFM are verified with a certified metrological test rig;
• full set of high-quality mounting accessories;
• great operating experience;
• high-quality technical support;
• affordable price.
