Equflow Brass Turbine Flowmeter

The Brass flow sensor of Equflow has low flow sensing capabilities in a wide range of applications suitable for neutral, aqueous and opaque liquids including fuel. An ultra light-weight turbine rotor follows the fluctuation of the flow very accurately and generates a high resolution IR-reflected digital output signal. In either flow controlled or monitoring applications, the Brass flow sensor can measure flow rates and totalize.

  • Brass Turbine flowsensor with high resolution output
  • Measuring by revolutionary IR Turbine reflection
  • High accuracy and repeatability
  • Also suitable for opaque liquids
  • All wetted parts are made of Brass, PVDF with ruby bearing and FPM (Viton®) sealing


  • Programmable K-factor
  • Flow alarm level
  • Batch function with preset
