Light weight, small size, easy to install.Hall element is imported, water-proof design to prevent water ingress,The inside of the impeller is inlaid with a stainless steel shaft and is always wear-resistant. Plastic made, explosion-proof, heat and cold resistant. Three wire connection: Red for positive, black for negative, yellow for pulse signal. The water flow sensor is applied for water heater, and can be used as flow switch. Maximum water pressure: 1.75MPa, flow range: 1-30L/min. 1. The Water Flow Sensor is light, nimble outline, small size and easy to install. The bearings used in the rotating part.
2. There is an integrated magnetic hall effect sensor that outputs an electrical pulse with every revolution. The hall effect sensor is sealed from the water pipe and allows the sensor to stay safe and dry.
3. Three wire connection: Red for positive, black for negative, yellow for pulse signal.
