ABSTRACT:
The invention provides a sensing device and method to determine irregularities of a pipeline wall arising from corrosion, pitting, gouges, scale and deposits, and dents causing out of round conditions. This sensing device may be carried through a pipeline by a pipeline pig and comprises radial, movable spring-loaded sensing fingers adapted to continuously contact the pipeline inner surface, said sensing fingers preferably being secured to a fluid-tight drum. The sensing fingers are acoustically connected to one or more microphones, which may be confined within the interior chamber of the fluid-tight drum. The microphones, in turn, are electrically connected to a recording device for recording the audio signal the sensing fingers make as they move through the pipeline.
