Alternate Current Voltage Gradient (ACVG) Equipment

Alternate Current Voltage Gradient (ACVG) Equipment
Explanation

PCMx: the faster, more convenient survey system for corrosion control.

Working alongside industry experts, Radiodetection pioneered the first Pipeline Current Mapper over 20 years ago. It enabled surveyors to identify possible sources of external corrosion on inaccessible pipelines, including those buried beneath rivers and highways. Since then, it has become the tool of choice for many organisations to locate and pinpoint pipeline coating defects.

PCMx builds on this pedigree, harnessing the power of Radiodetection’s most advanced locator technologies to deliver faster results, simultaneous survey measurements, and integrated GPS positioning.

Faster surveying for quicker results

Increasing number of pipelines, aging infrastructures and more rigorous guidelines result in growing pressure for corrosion specialists to complete surveys and analyse results quicker. The new PCMx system has been designed to meet these challenges with faster measurements and greater portability.

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.

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.

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.

Transmitters for distribution and transmission lines

For distribution lines, the Tx-25PCM delivers up to 1 Amp of output. This lighter, battery powered transmitter provides extra portability and flexibility in the field. An additional 8kHz high frequency locate signal is provided for long distance, high impedance utility locating. The long range Tx-150PCM transmitter is ideal for transmission lines with up to 3 Amp output and a signal range of up to 30 km.

The PCMx mobile application allows on-site analysis and allows the operator to examine these analyzes as they progress through the measurement area. The collection of data by combining one-second mapping measurements simultaneously with ACCA and ACVG makes measurements faster.
