Item Type: Water Flow Sensor Switch Model: FS G1/2 double male thread Working Voltage: DC 0-210 V Working Current: 0.5-1 A Working Temperature: -10 to 85 °C Maximum Temperature Resistance: 85 °C Working Pressure: 0.2 MPa Medium Specific Gravity: 0.7 Thread Size: Double male thread G1/2 Minimum Starting Flow: 0.75 L/min Maximum Throughput: 5 L/min Rated Working Pressure: 0.65 MPa Maximum Pressure of the Shell: 1.5 MPa Signal Output Load: DC 24V/0.5A, 36V/0.5A or AC 220V/0.1A Adaptation Scope and Conditions: (1) The ambient temperature must not be lower than 0 °C. Do not strike the case. Keep away from magnetic objects. (2) The signal output is a switch value; the connected control object must support switch control. (3) The power of the control object must not exceed the signal load capacity. (4) This device is designed for water medium only and cannot be used for other media. When the water flow in the pipeline exceeds 0.75 L/min, the magnetic core displaces under water flow force and drives the magnetic source to generate a control action, causing the sensor to output a "1" switching signal. After signal amplification, flow control is achieved. When the water flow drops below 0.75 L/min, the return spring drives the magnetic core back, causing the sensor to output a "0" switching signal to stop the system. Recommended for use with small relays.
