DFM autonomous fuel flow counter. Simple solution for fuel monitoring.

Autonomous fuel counter DFM is a simple solution for fuel consumption control.

Fuel counter DFM can be used to create a fleet fuel consumption accounting system.

Fuel flow counter DFM represents information on the LCD display. Fuel consumption indications control and fixation are made visually by a responsible person with entering data to report.




It is supposed to use GPS trackers to organize the fuel consumption accounting system in a company. The application of DFM counters is a simpler and cheaper way to do it. The fuel consumption accounting system based on the autonomous fuel counter DFM is easy to install and maintenance. There is no need any additional costs for hardware and software.

Fuel flow counter DFM is powered by built-in battery. Its resources are enough for more than 24 months of the device continuous operation. The fuel counter DFM has no buttons - switching on the display is made with a special magnetic key.

The unique tampering and intervention protection functions of fuel counter DFM allow using it in companies, where the chances of vandalism and discredit from some drivers are high.

If somebody will try to blow DFM with the air, the air volume passed through the device would not considered in the counter of consumed fuel, but will get into special counter called "Tampering".

The counter "Interference time" will protect from attempts to influence the device with a magnet. It registers the duration of exposure to the device with the magnetic field.

Along with the fuel monitoring function counters DFM have a function of engine operating time control (DFM C model ). This functionality is very useful for some kinds of machines.
