The vLocDM2 (Defect Mapper) uses the latest locating and signal processing techniques to plot the current gradient of an industry standard low frequency (3Hz or 4Hz) profiling current. The current is applied at CP stations, so the disruption of the pipeline can be minimized.
The non-intrusive measuring device, the vLocDM2 receiver, takes measurements along the pipeline and plots the results directly onto the screen of the receiver. There is no need to carry extra logging and display devices. All the data is displayed and logged into the receiver for downloading to a spreadsheet or dedicated analysis program.
A +/- 3m accuracy GPS antenna comes with the system and is linked to the vLocDM2 receiver via a Bluetooth radio link. The GPS enables the user to generate real-time current gradient graphs and guides the user back to the point of interest by highlighting the user’s position on the graph. This feature is called the “walk back” feature. The system can also be integrated with brand-named high accuracy GPS systems and software packages.
The Loc-150Tx, 150W transmitter (vLocDM2 transmitter) is used to apply a signal current to the anode bed. The pipeline returns the signal via coating faults back to the transmitter. The transmitter is designed to be powered from CP (Cathodic Protection) stations, AC or external batteries, eliminating the need for batteries.
