Description
technical field [0001] The invention relates to a data acquisition technology for equipment leakage caused by corrosion, in particular to a multi-channel industrial monitoring system for oil storage tank bottom plate leakage. Background technique [0002] In recent years, with the increasing demand for crude oil in the domestic and foreign markets, oil refineries have continuously increased their requirements for the storage and transportation of crude oil and refined oil products, and related oil storage tank leakage detection and anti-leakage technologies have been widely used. A crude oil processing, storage and transportation enterprise has adopted a double-layer tank bottom structure to reduce oil leakage and environmental pollution, and installed corresponding testing equipment to detect oil leakage points, but the tank bottom testing equipment has large volume, complex structure, The disadvantage of low sensitivity. Therefore, the study of a new generation of tank bo...
