1、The flow switch has high sensitivity and durability 2、The flow switch consists of magnetic core, return spring, wrought copper or polycarbon housing and sensor 3、The shell is made of H58 forged copper or polycarbon, the core is made of NdFeB permanent magnet, and the sensor magnetic switch is a high-quality power component 4、The inlet and outlet ports are all G1/2in standard pipe threads, tight connection and stable performance 5、Suitable for water circulation control, water inlet and outlet control, water heating control, pump switch control, solenoid valve on/off control, water outlet power outage, water outlet power control, etc. 2 x Water Flow Sensor Switch Item Type: Water Flow Sensor SwitchModel: FS G1/2 double male threadWorking Voltage: DC0-210 (V)Working Current: 0.5-1 (A)Working Temperature: -10 ~ 85(℃)Maximum Temperature Resistance: 85(℃)Working Pressure: 0.2 (Mpa)Medium Specific Gravity: 0.7Thread Size: Double male thread G1/2Minimum Starting Flow: ≥ 0.75L / minMaximum Throughput: ≤5L / minRated Working Pressure: ≤ 0.65MpaMaximum Pressure of the Shell: ≤ 1.5MpaSignal Output Load: DC24V/ 0.5A, 36V/ 0.5A or AC220V/ 0.1AAdaptation Scope and Conditions: (1) The ambient temperature is not lower than 0℃. Do not knock on the case. Keep away from magnetic objects.(2) The output of the signal is a switch value, so the connection method of the control object must also be a switch control relationship.(3) The power of the control object must not be greater than the signal load capacity.(4) This device is a water medium control device and cannot be used for other medium control.When the water flow in the pipeline is greater than 0.75L / min, the magnetic core will be displaced under the action of the water flow and drive the magnetic source to generate a magnetic control action to cause the sensor to output a "1" switching signal. After expansion and amplification, the purpose of water flow control is achieved. When the water flow in the pipeline is less than 0.75L / min, the magnetic core will drive the magnetic source back under the force of the return spring, causing the sensor to output a "0" switching signal to stop the system. Recommended for use with small relays
