F3.20 Paddlewheel Flow Sensor

2.2. Operating Principle
The flow sensor consists of a transducer and a five-blade open cell paddlewheel using
insertion technology. The paddlewheel is equipped with a permanent magnet
integrated into each blade. As the magnet passes close to the transducer a pulse is
generated. When liquid flows into the pipe, the paddlewheel is set in rotation
producing a square wave output signal. The frequency is proportional to the flow
velocity. The sensor is installed into the pipe using a wide range of insertion type
fittings supplied by the flow sensor manufacturer.
