Technoton DFM Fuel Flow Meter

DFM is designed for fuel consumption measurement in fuel lines of vehicles and stationary machines, also for operating time monitoring in different working modes of engine.

Description

DFM is designed for fuel consumption measurement in fuel lines of vehicles and stationary machines, also for operating time monitoring in different working modes of engine.

DFM fuel flow meter is used for consumption measurement of the following fluids:

  • diesel fuel
  • heating oil
  • other liquid fuels and mineral oils with kinematic viscosity of 1.5 to 6 mm2/s.

DFM is a tool for direct measurement of fuel consumption, which is used as a part of GPS tracking system, vehicle telematics system or as an stand-alone (autonomous) solution for fuel consumption monitoring.

One-chamber DFM fuel flow meters are mainly intended for small and medium engines with indirect injection fuel system.

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.
