Product Description

SAIER’s water flow sensor is made of high-quality copper material, consists of a brass body, a water rotor, and a hall-effect sensor. The integrated hall effect sensor outputs the corresponding pulse signal with every revolution and is sealed from the water pipe and allows the sensor to stay safe and dry.
The theory is simple: when water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs an electrical pulse with every revolution.
The sensor is very sturdy and durable to use, its maximum water pressure is 1.75MPa. With lightweight and has compact size, stable performance, low water pressure start, very easy to install and safe to use.
And it can be perfectly used for water heaters, water dispenser, water purifier, water vending machine, coffee maker, flow measurement device, water control machine and so on.
