[0002] In the petrochemical industry, there are a large number of storage tanks as storage devices for oil products. In order to reduce the volatilization of oil and gas from light oil products and reduce the pollution of oil and gas volatilization to the atmospheric environment, the petrochemical industry often uses floating roof tanks to store light oil products.

[0003] The floating plate in the tank is affected by the buoyancy of the float and floats on the surface of the oil. It rises and falls with the oil level, leaving no space for the liquid phase to evaporate, which can effectively reduce the evaporation loss of the oil. However, the floating plate of the floating roof tank has the risk of tilting and even getting stuck during the long-term lifting process, which is prone to safety accidents and economic losses. The existing floating roof tank liquid level detection system only detects the oil liquid level, and usually ignores the detection of the tilt of the floating plate. Utility Model Content
