The FineTek SF1800 Vane Type Flow Switch precisely detects liquid flow within pipes by responding to paddle movement. When there is no flow or liquid is static, a spring fully extends, pulling the magnet down and opening the switch. As liquid flow pushes the paddle forward 20°~ 30° or more, it drives the magnet upward, closing the switch and completing the circuit. The paddle length can be customized to fit various pipe diameters, ensuring accurate and reliable flow detection across different applications.
