["Description : \r\nWater Flow sensor includes a plastic body housing, a water rotor, and a hall-effect sensor, PCB electronics board\r\nWorking performance : When the water flows through the rotor, then rotor is rolled\r\nIts speed changes with different rate of flow. Then the magnetic rotor make reaction to Hall sensor,\r\nthe hall-effect sensor outputs the corresponding pulse signal\r\nThe flow sensor is suitable to detect the flow in water dispenser or coffee machine .....\r\n\r\nSpecification:\r\nMaterial : Plastic\r\nColor: White\r\nFunction: Sensor, flow rate control\r\nFlow Rate: 0.3~3 L/min\r\nFlow Pulse: F(Hz)=(109xQ) L/min +/- 5 %\r\nMax. Working Current : 15mA (DC5 V)\r\nMin. Working Voltage: for DC 4.5V\r\nWorking Voltage: for DC 5V~24V\r\nLoad Capacity: =10 mA (for DC 5 V)\r\nPressure: 0.8mPa\r\nOperating Working Temperature : -25~+60℃\r\n1 Litter water =7055Pulse +/-10%\r\nAccuracy :+- 5% \r\nWorking environmental: Water, liquid, light oil, beer, drinking water\r\nConnect Pipe Diameter: 6mm or 1/4\"\r\nInner Diameter: 58.4mm/0.23\"\r\nOuter Diameter: 12.2mm/0.48\"\r\nQuantity: 1 Pc\r\nNote:\r\nPlease allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bid\r\nDue to the difference between different monitors, the picture may not reflect the actual color of the item.
