Abstract
A magnetic flux measurement apparatus and method for nondestructive thickness imaging of metallic objects. The apparatus can primarily be used for thickness imaging of concentric metallic pipes, such as inner tubing and outer casing pipes in downhole applications. The magnetic flux measurement apparatus includes a transducer that includes a magnetic field source, magnetic flux sensor rings and a magnetic flux guide lens both positioned in alignment with a lateral axis of the magnetic field source. The magnetic flux guide lens is made of ferromagnetic material with high magnetic permeability that can direct flux lines into a predetermined sensor area for higher sensitivity and signal to noise ratio.
