Abstract
Acoustic emissions are detected so that the amount of wear on the interior of a conduit can be directly determined. The acoustic emissions arise from plastic deformations and fractures caused by the fluid and particulate substances therein flowing through the conduit and impinging upon the interior surface of the conduit or by cavitation. The apparatus as disclosed has the capability to detect and also locate the surface area where wear is occurring.
