However, in actual use, it faces many problems due to the influence of the characteristics of the measured medium and the working environment. For example, solid particles, viscous substances or chemical reaction residues such as unreacted monomers and polymers in polymerization reaction may adhere to the inner wall of the main pipe and the surface of the float of the liquid level meter. In food processing such as dairy production, protein and fat may form dirt in the liquid level meter. The accumulation of these impurities and dirt hinders the normal lifting of the float and interferes with the magnetic coupling, causing the magnetic float to turn abnormally, which affects the accurate control of production.
