Счетчик-переключатель расходомер водонепроницаемый расходомер Воды Импульсный Датчик Холла термостойкость

Description:
100% brand new and high quality!
The water flow sensor is mainly composed of a plastic body, a water flow rotor assembly and a Hall sensor.
It is installed at the water inlet of the water heater to detect the influent flow.
The product is light and flexible in appearance, small in size and easy to install.
The inside of the impeller is inlaid with a stainless steel shaft, and the upper and lower penetrating and dispersing force points are always wear-resistant.
The sealing ring is made of nitrile rubber, and the structure of the upper and lower forces will never leak.
The Hall prevents water from entering and never ages.
As the water passes through the water flow rotor assembly, the magnetic rotor rotates and the rotational speed changes as the flow changes.
The Hall sensor outputs the corresponding pulse signal and feeds it back to the controller.
The controller determines the magnitude of the water flow and performs regulation.
