Abstract
A system for ascertaining the existence and location of anomalies along the length of a member, such as an underground pipeline. Electrical pulses are imparted to the pipeline at opposite ends thereof, with these pulses being synchronized so that they meet at predetermined locations along the length of the pipeline. The wave form of one of the pulses which has passed through the point of intersection is analyzed to determine the possibility of an anomaly being present at the location of intersection. These readings can be correlated to half-cell readings which could be taken along the pipeline as a means of analyzing pipeline conditions.
