Design of MFL Inspection Device for Underground Oil Tanks Based on Independent Calibration Method

Article Preview

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 the inspection device was established. Through comparison of channel independent and identical calibration methods, the experiment result using channel independent calibration method has better precision of about 1/3 discovery rate.
