The Kelco P20 Series Flow Switch is a robust, highly reliable solution for detecting low flow rates of liquids or gases in small-diameter piping. Built with no metal parts in contact with fluid, it’s ideal for corrosive or aggressive media like acids, seawater, or chemical solutions. Designed for all-position mounting, it functions effectively in any orientation—including upside down.
This compact, 18 BAR-rated switch provides stable, low head-loss performance and responds to continuous or pulsed flows. Commonly used in chemical dosing, irrigation systems, chilled water control, and industrial processes, the P20 offers a simple on/off signal via magnetically actuated reed or solid-state switches.
Made from glass-reinforced polypropylene with Nitrile seals, the P20 ensures long service life in harsh environments. Its modular electrical design allows selection from SPST, SPDT, or solid-state relay options, making it a versatile and dependable component in automated systems and control panels.
