Given the large service area of a tank floor, the typical in-service condition of the scanning surface, and the general working conditions inside a storage tank, the inspection method identified to detect underfloor corrosion must be fast, robust, reliable, and provide a high value of confidence for minimum detectability. Magnetic flux leakage (MFL) systems have been historically deployed for this part of the inspection process, and the technology has a proven track record for being able to provide consistent results within these harsh and uncomfortable environments. MFL as a technology has numerous deployment applications; however, this article specifically considers the use of hall effect sensors to measure flux leakage changes in order to
determine the severity of corrosion.
