A pipeline pig adapted to carry inspection components to determine flaws in a pipeline wall arising from corrosion, pitting, gouges, hard spots, scratches, metallurgical anomalies and dents causing out of round conditions is equipped with an accelerometer. The accelerometer is adapted to provide an electrical signal indicative of acceleration and deceleration in the direction parallel to the axis of the pipeline. By correlation of signals recorded by the flaw detection equipment with signals recorded from the accelerometer, dents may be readily identified. |
