RSA-TVW Paddlewheel Flow Transmitter
Applications & Features
- For monitoring liquid flow rates in pipes from 1-1/2 to 40˝ , integral 4- 20 mA output
- Bearings and shaft offer excellent wear protection even in applications with particulate for long life
- One unit adjustable over a large pipe size range
- Sensor technology uses inductive sensing to sense the blades of the impeller therefore does not use magnets allowing low flow rate monitoring with no concerns regarding magnetic material in the flow
