Item Type: Water Flow Sensor Switch Model: FS G1/2 double male thread Working 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: 0.7 Thread Size: Double male thread G1/2 Minimum Starting Flow: 0.75L / min Maximum Throughput: 5L / min Rated Working Pressure: 0.65Mpa Maximum Pressure of the Shell: 1.5Mpa Signal Output Load: DC24V/0.5A, 36V/0.5A or AC220V/0.1A Adaptation 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
