A simple sensor for measuring the flow of liquids. Consists of a pinwheel that has a magnet and Hall sensors. By counting the pulses of a hanging fan, in a simple way, you can measure the flow of liquids. With this method, the electronic part of the sensor has no contact with water.


The device has three wires:

  • red- supply voltage from 5 V to 24 V
  • black- ground
  • yellowpulse output signal 


By counting pulses you can track the fluid flowin a simple way. It should be noted that this is not a sensor for precision measurements. However, it is ideal for use in hobbies that do not require greater accuracy than 10 %.


The product is compatible with Arduino

The manufacturer provides a sample program for Arduino with connection diagram. The project is available inthe user's guide.
