When water goes through rotor subassembly, magnetic rotor rotates and rotating speed changes with the . Hall sensor outputs corresponding pulse signal as feedback to controller and controller judges water amount and adjusts . Features: This sensor meter is lightweight, small and easy to install. The internal impeller has stainl steel shaft which is quite wear-resistant. ring uses mechanical structure that stred from up and down directions and will not leak. The sensor has Hall effect element and is encapsulated with glue, preventing from water entering. It is a great sensor of high precision, long service life and stable performance.
