Pipeline Current Mapper, Model PCMx

Locates and effectively measures pipeline coating faults.



Radiodetection’s PCMx system enables corrosion and Cathodic Protection System (CPS) professionals to evaluate the condition and effectiveness of pipeline coatings.  Users can locate faults and holidays in the coatings, and identify shorts caused by contact to other structures.

PCMx enables pipeline managers to identify and prioritise preventative maintenance on pipelines; extending asset life by identifying possible sources of corrosion at an early stage. 

The system can be used to conduct ACCA and ACVG surveys in accordance with ANSI/NACE SP0502-2010 ‘Standard Practice for Pipeline External Corrosion Direct Assessment Methodology’. These surveys, which may be conducted separately or simultaneously, can be used to locate and pinpoint coating defects or identify shorts made by contacts with other structures. 

Removal of the detachable foot leaves a fully-featured RD8100PDLG pipe and cable locator. Depth of cover and GPS positional data is also captured. 

  • Faster results
    A mobile (Android) companion app allows users to chart results in the field improving on-site analysis. Walk back and walk forward features gets you to your next measurement quicker. An additional PC app offers improved charting tools.

  • One second mapping measurements
    With each mapping measurement now only taking one second, survey times are reduced. Integrated GPS ensures each measurement is captured with positional data.

  • Two surveys in one pass of the pipeline
    Conduct both ACCA and ACVG surveys with one pass of the pipeline. PCMx allows you to collect both measurement types simultaneously, reducing survey time and getting results faster.

  • More information at your fingertips
    Radiodetection’s Peak+ technology guides you to your target pipeline quicker while the compass display ensures correct alignment. Simultaneous depth and current measurements give you confidence you are following the correct line.

  • Improved ergonomics
    With a balanced design and lighter weight, (2.2kg, 4.8lb), the receiver is easier to carry over long distances. The convenience of a Li-Ion rechargeable battery pack ensures extended runtime. 


One second mapping measurements combined with simultaneous ACCA and ACVG data gathering makes surveying faster.
