HL-YFSDN32 series industrial large flow water flow sensor swimming pool water flow meter
Product introduction
The water flow sensor is mainly composed of a plastic valve body, a water flow rotor assembly and a Hall sensor. It is installed on the water pipe to detect the inflow flow. When the water passes through the water flow rotor assembly, the magnetic rotor rotates and the rotation speed changes with the flow rate. The Hall sensor outputs a corresponding pulse signal and feeds back to the controller, which is judged by the controller. The amount of water flow is regulated.
Features
1. This product is light and flexible in appearance, small in size and easy to install.
2. The impeller is internally set with a stainless steel shaft and stainless steel beads to assist in rotation. Thereby improving the sensitivity of the rotator.
3. The sealing ring adopts the upper and lower force structure without water leakage.
4. The Hall element is imported from the United States and is packaged in an O-type waterproof apron imported from Japan. The outlet is made of waterproof silicone to enhance waterproof. (Customized circuit board is fully sealed and waterproof.)
5. All raw materials are in compliance with ROHS testing standards.
