On-Board Volumetric Flow Detector

 

 

The FP-4135 On-Board Volumetric Flow Detector is the high-precision positive displacement flow detector to measure the fuel flow rate of liquids such as gasoline, light oil and kerosene combined with the Ono Sokki DF-2200 On-Board Flow Meter or the FM series Digital Flow meter.


Because the flow rate range is as wide as 0.1 to 200 L/h (measurement range ratio 2000:1), it can measure from very low flow rate in an idling state to large amount of flow rate in a high-load state when a fuel with a low heating value such as alcohol is used.


Also, since the flow detecting part is compact and its operating temperature range is -30 to +100°C, it can be installed inside an engine room to measure the actual driving fuel efficiency.

 

 

 

Features

  • High precision
    Measurement range : 0.1 to 200 L/h
    Accuracy                    : ±0.2 %
    Resolution                 : 0.01 mL
  • Wide temperature range
    Designed to support temperature variation in an engine room, and environmental test
    Wide temperature range from -30 to 100 ℃
  • Compact body
    Built-in temperature sensor which is required for fuel consumption measurement and downsized filter enable 70% reduction in volume. (Compared to main unit of the FP-2140H of Ono Sokki, excluding signal processing part.)
  • Supports wide variety of fuels
    It can measure a variety of fuels including gasoline, alcohol, and light oil etc. as standard.
