UZC cryogenic magnetic level gauge is suitable for low temperature and ultra low temperature liquid measurement. The lowest working temperature can reach -196 ℃. The product chamber adopts the most mature cryogenic isolation technology at present, which can make the level gauge normal in low temperature environment for a long time. It has the advantages of no frost on the surface, no dead zone in the whole process measurement, eye-catching display, intuitive reading, and large measurement range. According to the working temperature, it can be divided into low temperature type and ultra low temperature type. These two types of level gauges use different cryogenic isolation processes to achieve the corresponding temperature measurement.
