It is installed at the water inlet end of the water heater to detect the flow rate of the inlet water. When the water passes through the water flow rotor assembly, the magnetic rotor rotates, and the speed changes linearly with the flow rate. The Hall sensor outputs the corresponding pulse signal and feeds it back to the controller. The controller judges the size of the water flow and regulates it. Output signal: the default output NPN pulse signal Interface size: 1/4" 3/8" 1/2" Working voltage range: DC 5-18V Material: Aluminum alloy Medium temperature: 120 Water pressure resistance: 1.75MPa Output pulse high level: >DC 4.5V . Output pulse low level: 100M Flow range: 1/4" 30~300L/H, 3/8" 40~800L/H, 1/2" 50~1200L/H Tightness: Close each hole, add 1.7Mpa water pressure test for 1 minute without leakage and deformation. Flow pulse characteristics: 1/4" F=±1%, 3/8" F=±1%, 1/2" F=±1% Q = L/Min. Notice: 2. Package list: Water flow sensor*1pc 3.
