Water Flow Sensor
Product Description
Water flow sensor mainly consists of plastic valve body, water flow rotor assembly and hall sensor. Installed Water Flow Sensor to the inlet end of the water heater, to detect the rate of inlet water flow.
When water passes through the Water Flow Sensor rotor assembly, the magnetic rotor rotates and the rotating speed changes with the flow rate.
Hall sensor outputs the corresponding pulse and feed back to the controller, which determines the flow range of water and regulates.
The pulse signal output, can be used for water flow switch, also can be used to measure the flow. Water Flow Sensor meter for showerroom credit card system, have two flow range.
If you want to increase the temperature control, you can add heat sensitive resistor,the output line is green, but also can be connected to the other two special line to control temperature.
We have two flow range2-45L/Min and 2-60L/min.
