The PFA/Teflon® Turbine Flow meter with infra red reflection measurement, has low flow sensing capabilities in a wide range of applications, and is suitable for clear-, opaque, neutral, corrosive and aggressive liquids including fuel.
An ultra light-weight turbine rotor monitors the fluctuation of flow very accurately and generates a high resolution IR (Infra Red) reflected digital output signal.
In both flow controlled and monitoring applications, the PFA flow sensor can measure flow rates and totalize.
- High resolution, proportional to the flow
- Highly chemical resistant
- Splendid accuracy and repeatability
- Can be used for opaque liquids
