✅ Features
▶️1. This product has a light and flexible appearance, small size and is easy to install.
▶️2. The impeller is inlaid with a stainless steel shaft, which penetrates up and down to disperse the stress points and is always wear-resistant.
▶️3. The sealing ring is made of butyl rubber imported from Japan, and the structure with upper and lower forces will never leak.
▶️4. The Hall element is imported and sealed with potting glue to prevent water ingress and never age.
▶️5. All raw materials comply with ROHS testing standards
✅ 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 at the water inlet end of the water heater and is used to detect the water flow. When water passes through the water flow rotor assembly,
▶️The magnetic rotor rotates and the speed changes with the flow rate, and the Hall sensor outputs corresponding pulses
▶️The signal is fed back to the controller, which determines the water flow rate and regulates it.
✅ Precautions for use:
▶️Severe impact and chemical corrosion are strictly prohibited.
▶️Throwing or collision is strictly prohibited.
▶️The medium temperature should not exceed 120 degrees.
✅ Lead-out method:
▶️1 Red IN connects to the positive pole
▶️2 Yellow OUT signal output line
▶️3 Black GND connects to the negative pole
