Features of Fuel Flow Meter

  • Pulse output for remote readout
  • Indication in:
    - Actual Flow(l/h)
    - Consumption in normal mode (l)
    - Consumption in overflow mode (l)
  • Strong metal moulded case
  • Flow meter design provides a fuel flow even when measuring ring has stopped
  • Ease of mounting and operation
  • Engine operating time
  • Engine working time in "idling" mode
  • Engine working time in "optimal" mode
  • Measuring chamber temperature
  • Consumption in overload mode
  • 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
  • Wide clearing section minimizes
    hydraulic resistance of fluid flow
  • Sustainable product design:
    - Low battery indication
    - Low power consumption
    - Lightweight and compact

Flow Range





DFM-50C-K 1 l/h 50 l/h 80 (kW)

Interference Protection


Security Method

Tampering detection If flowrate is higher than 2x nominal flowrate the "fuel consumption counter" does not count but the "tampering mode" counter counts.
Magnetic field interference Special reed switch is activated when exposed to static magnetic field interference for more than 5 seconds and the time of interference is counted by "interference time" counter.

Supply power switched off
Embedded battery supplier autonomous operation of the flowmeter up to 2 years
Disconnection from the fuel system
Installation kit elements have openings for sealing.



Technical Specifications



Acceptable liquids diesel, fuel, petrol*, mineral oil. Other liquids with kinematic viscosity from 1.5 to 6mm2/sec are possible but maximal flow rate could be lower than the specifiedflow range and pressure drop over the instrument can be higher.
Operating Pressure 2 .. 25 bar(a)
Operating temperature -20 .. 60 °C
Accuracy ± 1% RD
Humidity 95% at environmental temperature of 40 °C
with acceleration of 100 m/s2 in frequency range of 5 .. 250 Hz
Aggressive environment steady to fuel and lubricant materials

* FUEL-VIEW fuel flow meters are manufactured of petrol-proof materials. While working with petrol, national legislation safety measures must be applied and the declared lifetime of the measuring chamber of the flow meter is not guaranteed.
