Technoton DFM Marine Flow Meter

DFM Marine is used in telematics systems (GPS tracking systems) and as an autonomous fuel monitoring solution.


DFM Marine is used in telematics systems (GPS tracking systems) and as an autonomous fuel monitoring solution. DFM Marine is installed in fuel line of the engine / boiler / burner, directly measures fuel consumption and generates an output signal, which is sent to telematics unit (GPS tracker).




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.
