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 infrared-reflected digital output signal. 

In either flow controlled or monitoring applications, the brass flow sensor can measure flow rates and totalize.

The Brass flowmeter is designed for long term use with a robust housing.
Features
  • Infrared (IR) turbine rotor reflection results in accurate and repeatable flow measurements 
  • High chemical resistance 
  • High resolution square wave output  
  • Wetted parts made out of PVDF, brass, ruby bearing, and FPM (Viton®) sealing 
  • Outstanding performance in fuel measurement applications
