Measuring principle:
The liquid flowing into the turbine flow sensor is split by the blade in partial jets. These hit uniformly from different directions on the impeller and make this in rotation. The speed of the impeller is now converted into an electrical pulse signal (frequency): The impeller is magnetized, a Hall effect sensor detects the rotational movement. There is a flow proportional frequency signal (square wave signal) available. The geometry of the guide blading and impeller makes it possible to realize the very low start-up values.
