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 and never leaks. 4. The Hall element is imported from Germany and is encapsulated with potting glue to prevent water ingress and never age. 5. All raw materials meet 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 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, and the Hall sensor outputs corresponding pulses The signal is fed back to the controller, and the controller judges the size of the water flow and regulates it. Precautions for use: Severe impact and chemical erosion are strictly prohibited. Throwing or collision is strictly prohibited. Vertical installation, the inclination does not exceed 5 degrees. The temperature of the medium should not exceed 1200C. Output waveform: square wave Lead wire method: 1 Red IN to positive 2 Yellow OUT signal output line 3 Black GND connect to negative Pulse characteristics of inner diameter 2mm: F=73*Q (Q is flow rate L\/min) Error:  ±5 4380 pulses output after one liter of water flow, flow range 0.3-3L\/min Pulse characteristics of inner diameter 3mm: F=26*Q (Q is flow rate L\/min) Error:  ±5, output 1560 pulses after flowing one liter of water That is, frequency calculation = constant * unit flow rate (L\/min) * time (seconds) Flow range: 0.5-5L\/min technical parameter Scope of application: suitable for water heaters, credit card machines, automatic water vending machines, and other flow me.Find many great new \u0026amp; used options and get the best deals for High-Precision Flow Meter with Water Flow Sensor for Science\/arduino Projects at the best online prices at Order2india Shopping!
