Note: -AND More MORE PRACTICUM MODELS. Very suitable for those who want to learn. Product Description Product features: 1,this product appearance is light and agile,small volume,easy to install. 2 internal set with stainless steel shaft, impeller, wear forever. 3, sealing ring, the force of the structure under never leak. 4, hall element, USES the German import and encapsulated with potting glue, prevent water, never aging. 5,all raw materials meet ROHS testing standards Synopsis product: Water flow sensor is mainly composed of plastic valve body, flow of rotor components and hall sensors. It is installled in the water heater inlet, used to detect water flow, when the water through flow rotor components, Magnetic rotor rotation and speed changes with the flow, hall pulse output sensor Signal feedback to the controller by the controller to judge the size of the water flow, adjust and control. Use notice: It is spread to severe impact and chemical erosion. It is spread to throw or collision. Vertical installation, to no more than 5 degrees. Medium temperature should not be more than 1200 c. Second, the waveform output: square wave Three, lead way: 1 red IN connect the anode 3 black GND connect the cathode 4 green R temperature sensor (50 k, 3950 k or 3950 k please customers according to the requirements of them) Yf - S201 frequency: F = 7.5 x Q (L/Min) error: plus or minus 2% voltage: 3.5-24 VDC, current should not exceed 10 ma, 450 pulse output flow through a litre The frequency calculation = constant flow rate (L/min) 7.5 x unit time (in seconds) Working range: 0.3-6 L/min
