Item Type: Plastic Water Flow Sensor Switch Model: Fs-1 / 2-nylon Interface Thread Size: Male/Female threads are G1/2in Material: Nylon Working Voltage: DC 0-110V Working Current: 0.5-1A Medium Specific Gravity: 0.7 Signal Output Load: DC 24V/0.5A, 36V/0.5A Suitable Ambient Temperature: 1°C Suitable Working Temperature: 100°C Minimum Starting Flow: 0.75L/min Maximum Throughput: 5L/min Rated Working Pressure: 0.65MPa Maximum Pressure of The Shell: 1.5MPa Length: Approx. 64mm / 2.5in Working Principle: When the water flow in the pipeline exceeds 0.75L/min, the magnetic core displaces under water flow force and drives the magnetic source to generate a Hall effect, causing the sensor to output a "1" switching signal. This signal is sent to the equipment control system. After power amplification, water flow control is achieved. When water flow drops below 0.75L/min, the magnetic core returns via the spring force, causing the sensor to output a "0" switching signal to stop the system. Adaptation Scope and Conditions: (1) Ambient temperature must not be below 0°C. Do not strike the case. Keep away from magnetic objects. (2) The output signal is a switch signal; therefore, the connected control system must support switch control. (3) The power requirement of the controlled device must not exceed the signal load capacity. (4) This device is designed for water medium only and must not be used with other media.
