1, Lightweight appearance, small size, easy to install

2, The impeller embedded with stainless steel beads, always wearable

3, Isolation design of  circuit and water

4, Hall element

5, The valve body is made of transparent material to facilitate better observation of water flow and rotor conditions.

6, The materials are all in line with ROHS testing standards

Water flow sensor is mainly made of a plastic body, the rotor assembly and a Hall flow sensor.Water heater which is mounted on the end, for detecting the water flow, the water passes through the water when the rotor assembly,Magnetic rotor and change as the flow speed, the Hall sensor output corresponding pulse Signal, the feedback to the controller,

the controller determines the size of the water flow, for control.
