Radiodetection SPX PCM Plus Pipeline Current Mapper Locator Receiver PCM +

SPX PCM Plus Pipeline Current Mapper Locator Receiver

The location and measurement of pipeline corrosion using electromagnetic detection devices (Locators) are increasingly being linked with GIS systems and GPS information, to provide an accurate record of the condition of pipes and the position and time co-ordinates for post mapping analysis – this requirement is the basis of the PCM+.

As part of Radiodetection’s commitment to protecting the environment the PCM+ enables the pipeline technician to carry out preventative maintenance on pipelines giving them a longer life and identifying corrosion at an earlier stage.

The PCM+ System consists of a portable transmitter and a hand held receiver. The transmitter connected at the CPS station or test post, applies a special signal to the pipeline. The receiver locates this unique signal at distances up to 30km (19 miles) identifying the position and depth of the pipe.

Once the pipe has been located the technician can map the leakage currents along the pipe in magnitude and direction allowing coating defects to be quickly identified.

Once the segment of pipeline where the defect lies has been identified, by using an A-frame, the defect position and depth can be further pinpointed to within 1 meter (3 feet).

The PCM+ using its powerful feature set including Automatic Signal Attenuation (ASA), accurately and easily locates and maps the pipeline even in areas where there is contact with other metallic structures, electrical interference, or congestion, providing simultaneous measurement of PCM current (ACCA) and Voltage Gradient (ACVG).

This eliminates the need for the operator to perform ‘current spans’ and manual calculations to determine CP currents along a pipeline that would usually require a direct connection.
