Abstract
A device and method used for inspecting and measuring coiled tubing, production tubing or drill pipe as it enters the well. Defects such as internal and external wall loss, cracking and deformation can be detected and quantified. The axial motion of the tubing can be measured allowing for depth measurements that are more accurate and reliable than what can be obtained using an encoder wheel system.
