Abstract
The present invention determines the presence of a pig in a pipeline and the condition of the pig, as regards to the material the pig may be pushing, by passive acoustic detectors which determine the acoustic characteristics for the pipe and the pig. From these a computer is used to determine from changes in these characteristics the nature of the materials picked up by the pig or the condition of the pig and the pipe.
