1/2" 3/4" 1 Zoll Messing Hall Flow Sensor Wasserdurchflusssensor Durchflussmesser Steuerung Flüssigkeitssensorschalter

Produktbeschreibung

Description
The water flow sensor is mainly composed of a brass valve body, a water flow rotor assembly and a Hall sensor. It is installed at the water inlet end of the water heater to detect the water flow rate. When the water passes through the water flow rotor assembly, the magnetic rotor rotates and the speed changes with the flow rate. The Hall sensor outputs the corresponding pulse signal and feeds it back to the controller. The device judges the size of the water flow and regulates it.
Features
1. This product is light and handy in appearance, small in size, and easy to install.
2.The impeller is inlaid with stainless steel beads, which is permanent and wear-resistant.
3.The sealing ring adopts the structure of upper and lower force and never leaks.
4. The Hall element is imported with original packaging and is encapsulated with potting glue to prevent water ingress and never age.
5. Wide application scenarios, widely used in water heaters, drinking fountains, water vending machines, campus credit card machines
