Photo(Mass Flow Rate Measurement System)


This system uses two detectors, the FP-2140H volumetric flow detector and the FZ-2200 mass flow detector. Volumetric flow rate detected in high accuracy is converted to mass flow rate using density measurement values. Each value of the detector can also be displayed independently.


  • Continuous measurement without being affected by temperature, pressure or density
  • Wide measurement range (up to a ratio of 1000:1 within ±0.35% of reading accuracy)
  • Density measurement enabled.
  • Function for removing air bubbles in fuel supply
  • Provided an initial air purging device useful in replacement of a testing engine.
