Technoton DFM-D Differential Fuel Flow Meter

DFM D 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 GPS vehicle tracking system.

Description

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

Technoton

Technoton was established in April 2000, at the early stage of emerging market of automotive telematics and GPS tracking systems. We started with development and manufacture of GPS tracking devices, fuel level sensors and fuel flow meters. Soon we focused on solving tasks of fuel consumption measurement and fuel usage monitoring, safe CANbus data reading and analysis.

Technoton’s technical team includes highly-qualified engineers and developers, who have wide expertise in micro controller units, mechanical engineering, computer science, programming and diagnosis.
