This magnetic flap level gauge is a high-precision level measurement instrument based on the magnetic coupling principle. Constructed with 304/316L stainless steel and equipped with corrosion-resistant isolation diaphragms, it is directly compatible with level monitoring of various liquids (including corrosive, high-temperature/high-pressure media). Through the magnetic linkage between the float and the flap indicator, the device enables visual and intuitive level reading without measurement blind spots. It features wide temperature and pressure adaptability, low maintenance costs, and supports explosion-proof customization to meet the safety requirements of harsh industrial working conditions (e.g., flammable and explosive environments). With high measurement accuracy and stable display, it is a reliable choice for level monitoring in industrial processes.
