["Features:\r\n1. Stable, high temperature, low water pressure start, safe\r\n2. Detect whether the liquid flow line and traffic is to meet the requirements, at the same for time by switching electrical contacts provide a signal output ON or OFF state\r\n3. Equipment system by detecting the presence of a signal or a control current to pass therethrough (flow switch electrical contacts pass, off state) on the switch to determine the working status of the piping system\r\n\r\nPrinciple:\r\nWhen the water flow in the pipe is more than 0.75L / min, the core displacement under the action of water and promote the role of the magnetic source generates magnetic sensor outputs \"1\" switching signal, the signal input to the device control system, by expanding the power amplification to achieve the purpose of the water flow control. When the pipe in the water flow is less than 0.75L / min flow rate, the core magnetic source drive return under the action of the reset spring force, so that the sensor outputs \"0\" switch signal to stop operation of the system.\r\n\r\nSpecification:\r\nPower: 60-90W\r\nVoltage：AC 220V\r\nCurrent: 0.5A\r\nWater Temperature Range:≤100℃\r\nPressure:≤0.6Mpa\r\nFemale Port Thread Dia: G3/4\r\nMale Thread(Fit Pipe Dia): G1/2\r\nCable Length: 26cm\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. Thank you!\r\n\r\nPackage Contents:\r\n1x Water Flow Sensor Switch"]
