Equflow Stainless Steel Tri-Clamp Flowmeter

The Stainless Steel Tri-Clamp Turbine flow sensor has low flow sensing capabilities in a wide range of applications suitable for neutral, corrosive, aqueous and opaque liquids including fuel. Outstanding performance in high pressure applications. 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 Stainless Steel Tri-Clamp Turbine flow sensor can measure flow rates and totalize.

Outstanding performance for Sanitary applications in Food and Beverage, chemical industry and more. 


  • Stainless Steel Tri-Clamp Turbine flow sensor with high resolution output
  • Flow measuring with revolutionary Infra-Red turbine rotor reflection
  • Stainless Steel SS 316L – PFA for high corrosive resistance
  • Outstanding performance for high process pressure
  • High accuracy and repeatability
  • Also suitable for opaque liquids
  • All materials high chemical resitant

All wetted parts are made of SS.316L / PFA with ruby bearing
and FPM (Viton® ) sealing.
