What Does Pipeline Current Mapper (PCM) Mean?
A pipeline current mapper (PCM) is a corrosion monitoring type of equipment used to perform alternating current coating attenuation surveys. Results from this survey are then used to prevent pipeline corrosion.
A pipeline current mapper operates by measuring the electric current characteristics of a given section of an above-ground or underground pipe. The electric current over the entire length of the pipe is measured and charted. This useful information can be used to prevent corrosion.
