Product
Features
1. This product is light and handy in appearance, small in size and easy to install.
2.The impeller is inlaid with stainless steel beads, which is always wear-resistant.
3.The sealing ring adopts the structure of upper and lower force to never leak.
4. The Hall element is imported from Germany and encapsulated with potting glue.
Prevent water from entering and never age.
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 to detect the water flow rate. When the water passes through the water flow rotor assembly, the magnetic rotor rotates and the speed changes with the flow rate. The Hall sensor outputs the corresponding pulse signal and feeds it back to the controller. The device judges the size of the water flow and regulates it.
Product Precautions
1. Severe impact and chemical erosion are strictly prohibited.
2. Throwing or collision is strictly prohibited.
3. Vertical installation, the inclination does not exceed 5 degrees.
4. The temperature of the medium should not exceed 120
℃
