Apparatus and method of using accelerometer measurements for casing evaluation

A casing inspection device with magnets and flux sensors. Measurements of axial motion of the device are used to get better definition of the axial extent of casing defects. A contact device may be used for motion measurement. The output of the contact device may be used to control the acquisition o...
