The vLoc3-DM pipeline defect mapper by Vivax-Metrotech allows the user to collect current attenuation data and GPS data, and display that information on screen in a live graphical plot of the results. It locates pipeline, coating defects, and structural shorts using the latest locating and signal processing techniques to plot the current gradient of an industry standard low frequency (3Hz or 4Hz) profiling current. Pipeline defect mapper technology uses a current that is typically applied at CP stations so the disruption of the pipeline can be minimized.
The vLoc3-DM pipeline current mapper uses measurements taken along the pipeline and plots the results directly onto the screen of the receiver. Once collected, the data can be downloaded to a spreadsheet or dedicated analysis program.
