Water Flow Sensor

£3.99

In stock

This water flow sensor consists of a PVC body, a built in water rotor, and a hall-effect sensor. When water flows through the rotor, the rotor rolls and produces an output pulse signal, this signal then changes with different rates of flow. This sensor is suitable to detect fluid flow in water dispensers, greenhouse irrigation systems or coffee machines.
