Abstract
In this research, MFL inspection system has been studied for the inspection of storage tank floor. The reference specimens having 20%, 40%, 60% and 80% slot's are fabricated using the carbon steel plates of a 6mm and 10mm thick. Powerful permanent magnets and Hall effect sensors are used to this application. Also, this paper presents a newly developed MFL scanning system. Conclusively, it is shown that our system is able to detect metal loss like a slot.
