Fuel flow-meter
250 l/h | DFM-250D Mass Flow ONLINE BV

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 DFМ 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.

>Features
- Measures the differential fuel consumption of vehicles, where it is not possible to use the single-chamber fuel meter.
- Pulse output for remote readout. (For instance on-board controller with discrete or pulse input 0-32V).
- Can be used with vehicle tracking systems and fuel monitoring systems installed on motor vehicles with modern EURO (TIER) 3/4/5 diesel engines.
- Strong metal moulded case.
- Flow meter design provides a fuel flow even when measuring ring has stopped.
- Can be used with installation schemes with a supply- and return fuel line.
- Ease of mounting and operation
- Mounting in any position
- Built-in fuel filter
- Extended work range and accurate measurement ensured by digital
processing of signal
- Stable to vibrations and hydraulic shock
- Wide clearing section minimizes hydraulic resistance of fluid flow
- Sustainable product design:
