1/2" Water Flow Sensor Brass 1.75MPa Hall Sensor Turbine Pulse Flowmeter DC5~18V Used For Water Heaters Water Dispensers ,Energy-Saving

Package list: Water flow sensor*1pc

Product parameter

The water flow sensor is mainly composed of a brass valve body, a water flow rotor assembly, a steady flow assembly and a Hall element. It is installed at the water inlet end of the water heater to detect the flow rate of the inlet water. When the water passes through the water flow rotor assembly, the magnetic rotor rotates, and the speed changes linearly with the flow rate. The Hall sensor outputs the corresponding pulse signal and feeds it back to the controller. The controller judges the size of the water flow and regulates it.

Output signal: the default output NPN pulse signal (if you need to connect to the PLC, please contact customer service before placing an order).
