The oil pollution particles, sulfide gas, and humid air in the oil depot cause the precision of the pressure sensor to decrease and the service life to be shortened. The above problems make it difficult for the detection device to meet the 7x24 hour continuous monitoring requirements of the oil depot pipeline, and there is an urgent need to develop a new leakage detection technology scheme that combines convenient maintenance and high protection performance.
