Abstract
A tracking system for use with a pipeline includes a scraper having signal generation capability for generating acoustic signals, a plurality of acoustic pressure sensors positioned at intervals along the path traveled by the scraper, and a plurality of local processors positioned at intervals along the path traveled by the scraper. Each of the local processors is in communication with a respective acoustic pressure sensor. A central processor is in communication with the local processors and determines the location of the scraper using time-stamped acoustic signals received by the pressure sensors and a speed of sound, in a fluid within the pipeline.
