Working Principle

The medium flows through a specially shaped flow housing and causes a vane to rotate. Two magnets in the paddle wheel provide electrical pulses in Hall sensor. The frequency is directly proportional to the flow velocity. The evaluating electronic uses these signals for measurement, monitoring and batching.
