Abstract: The underground oil tanks are usually ellipsoid shaped and horizontal placed, in order to inspect the underground oil tanks using MFL method, a magnetization structure contains three sub parts was designed for curvature plates, the impact by the uneven placement sensors was analyzed, a new channel independent calibration method was raised. The calibration method, as well as the digital signal processing method was programmed in the inspection software, then a motor drive walking device was designed, at last th…
