Autonomous fuel flow counter

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

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

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

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

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

The special form to be filled out by a responsible person for fuel control.




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

If somebody will try to blow DFМ 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 (DFМ C model ). This functionality is very useful for some kinds of machines.
