1/4 & 3/8 Hall Flowmeter TDS / Temperature / Flow Three-in-one Multi-function Impeller Type Flow Sensor 1/4 & 3/8 Hall Flowmeter TDS / Temperature / Flow Three-in-one Multi-function Impeller Type Flow Sensor WATER FLOW SENSOR Itis mainly consists of pom valve body, rotor assembly and hall sensor. It is installed in the water inlet end for detecting water flow. When water flow through the rotor assembly, the rotor will rotate and it speed will change as the flow rate. The hall sensor outputs an electrical pulse with every revolution and feedback to controller/flow meter.It is suitable to detect flow in coffee, water, beer, RO filter machines.
