The PCM+ Pipeline Current Mapper System by Radiodection consists of a portable transmitter and a hand-held receiver. The transmitter is connected at the CPS station and applies a special signal to the pipeline. The receiver locates this signal at distances up to 30 km (19 miles) to identify the position and depth of the pipe.

Once the pipe has been located, the technician can map the leakage currents along the pipe both in magnitude and direction, and quickly identify coating defects. Once the segment of pipeline with the fault has been identified, the fault position and depth can be further pinpointed to within 1 meter (3 feet) by using an A-frame.

The PCM+ uses a powerful feature set consisting of Automatic Signal Attenuation (ASA), Advanced Current Direction (ACD) and Adaptive Ground Compensation (AGC). This allows the PCM+ to accurately and easily map the pipeline even in areas where there is contact with other metallic structures, electrical interference, or congestion, also to perform simultaneous measurement of PCM current (ACCA) and Voltage Gradient (ACVG). The PCM+ eliminates the need for the operator to make a direct connection and  perform "current spans" and manual calculations to determine CP currents along the pipeline.

In addition to being displayed on the receiver, all of the gathered data can be sent via Bluetooth® to either a PC or an optional PDA (with GPS), and then be displayed in a number of graphical formats for fast analysis. The PCM+ and its accessory equipment provide any pipeline technician with the latest in accurate, fast and reliable pipeline current mapping tools.

The location and measurement of pipeline corrosion using electromagnetic detection devices (Locators) must be linked with GIS systems and GPS to provide an accurate record of the condition of pipes and the position and time coordinates for post-mapping analysis. This requirement is the basis of the PCM+, which enables the pipeline technician to identify corrosion at an earlier stage and carry out preventative maintenance on pipelines to give them a longer life
