Volumetric Flow Detectors and Digital Flow Meters FP Series DF-220 and  FM3100

For use with diesel and petrol engines

A complete series of volumetric flow meters, used for measuring and controlling fuel consumption of various types of engines. They are highly accurate and cover a wide range of flow rate. Choose from small, medium or large flow rate measurement.


  1. FP-5130 Series - small flow rate
  2. FP-5140 Series - medium flow rate
  3. FP-5150 Series - large flow rate


These positive displacement flow meters are capable of making high precision measurement of different fluid flows ranging from micro to large capacity flows when used in combination with an FP-Series flow detector and a DF-Series flow meter.


You can choose the most appropriate item from our full line-up of the flow meters and counters to suit the applicable flow range, required measurement item and existing measuring site environments.

Volumetric Flow Detectors/Digital Flow Meters

DF220 On Board Flow Meter

The DF-2200 is a compact on-board fuel flow meter used in conjunction with the FP Series volumetric flow detectors. Accepts both pulse signal Sig A and Sig B and also comes with a backward flow correction function to minimise back-flow.


Measure the mass flow rate by simply entering the value of standard fuel density, temperature and density coefficient.


The DF-2200 outputs the voltage corresponding to the value of instantaneous flow rate/ temperature/ pressure, and outputs the pulse corresponding to the instantaneous flow rate. CAN and RS-232C (option) are also equipped with the external devices as a communication function.


The DF-2200 can measure both on-board measurement and measurement on engine bench.

  • Compact and easy to install in a vehicle
  • Flow rate/ temperature/ pressure measurement with one unit
  • Analog output with high-speed response
  • CAN output (standard) and RS-2232C (option) installed
  • Measurement time: every 1 sec update (instan) from start to stop (accum)

FM-3100 Digital Flow Meter

The FM-3100 digital flow meter is ideal for measurement in the small flow rate range with a fast response time.

  • Can be connected to FP-Series / FD-5110 / FX-Series / FZ-Series.
  • Fast response at 1ms (Analogue/CAN)
  • Density correction available via fuel temperature
