The sensitive device is installed at the lower end of the relay box, and the input component is a balance cover. The air duct (pressure guiding) is connected between the two, and the pressure of the liquid column is indirectly transmitted to the sensitive part through the air conduction through the air duct, thus avoiding direct contact between the sensitive part device and the measured medium. Not only suitable for measuring ordinary water, but also for liquid level measurement in special occasions such as high temperature, viscous, corrosive mediaSuitable for fields such as chemical engineering, metallurgy, power plants, water conservancy, urban water supply, and industrial wastewater.
