The component materials of the electric heat tracing magnetic float level gauge adopt 304, 316L, 321, 1Cr18Ni9Ti, 0Cr18Ni9, 00Cr17Ni14Mo2, 304 or 0Cr18Ni9 lined with PTFE (polytetrafluoroethylene), PVC, PP and other materials, as well as imported high-quality electronic components. The electric heat tracing magnetic float level gauge has high reliability, good stability, durability, and strong corrosion resistance. The electric heat tracing magnetic float level gauge has the advantages of simple structure, convenient use, high thermal efficiency, safety and reliability, no environmental pollution, long service life, and low maintenance workload. Electric heat tracing technology has been widely adopted. The electric heat tracing magnetic float level gauge is an advanced heat tracing system. Generally, electric heat tracing tape is bundled on the surface of the pipeline for heat tracing and insulation, ensuring that the liquid medium works at a certain temperature, so that the liquid level measurement of easily solidified and high-viscosity liquid media can be carried out normally. It is gradually replacing steam
