Specifications and Product Details:

Differential fuel flow meter DFM is designed for diesel fuel consumption measurement in the fuel line of vehicles

and installations.

Differential fuel consumption meter DFM may be used both with vehicle tracking system and fuel monitoring

system installed on motor vehicles with modern EURO (TIER) 3/4/5 diesel engines.

Differential fuel meter DFM is used to measure the fuel consumption of vehicles, where it is not possible to apply

the single-chamber diesel meter and the installation scheme with the return fuel line ringing.


Models
There are two realizations of the differential fuel flow meter, which differ in measuring chambers volume.
They are designed for different maximum flow rates measurement.

Operating principle
The operating principle of differential diesel meters is to calculate the fuel consumption as a difference between
the flow rates in supply and return fuel lines of the engine.

Differential fuel consumption meter DFM consists of two three-dimension ring type measuring chambers.
Each chamber generates the impulse, when the volume of fuel (which is equal to the measuring chamber volume)
passes through it. Electronic scheme is responsible for the impulses deduction and output impulses formation.
For the 1 liter of consumed fuel DFM generates the number of impulses, which is marked on the meter harness.

Mounting
Differential fuel flow meter is mounted into the fuel line of a vehicle without changing the fuel system scheme.

Differential diesel meter DFM can operate with GPS trackers which have discrete or pulse input 0-32V.
