vLocDM2 (Defect Mapper) - Pipeline Defect Mapper

Overview

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.

Features

  • Real-time on-screen mapping
  • Integrated GPS and Bluetooth
  • Low-frequency 3Hz and 4Hz current mapping
  • Identify the location of coating defects
  • Identify shorts to other structures
  • Operate as a long-line pipeline locator

Accessories

Remote Identification Antenna The Remote Antenna can be used to help identify a particular cable on a cable tray, where cables are bunched together, or in close proximity making it impossible to use a conventional locator. The flat surface of the remote antenna makes it useful for locating utilities behind walls. The remote antenna works in the frequency range of 512Hz to 200kHz.
Sondes Sondes are small self-contained battery powered transmitters. Sondes are propelled through non-metallic pipes and ducts and can be located on the surface by a sonde locator or buried utility locator with a sonde mode. Sondes are also built into other products such as a sewer push camera, robotic crawler camera, or attached to a jetter hose. Sondes come in a variety of sizes which ties into how deep they can be located. Different frequencies are available which allow sondes to be located in metallic or non-metallic pipes and ducts. Range of sizes and frequencies for different applications End Caps compatible with popular duct rodders Useable with other manufacturers utility locators Long battery life
vLoc2 Accessory A-Frame The vLoc2 Series Accessory A-Frame accessory is used to detect ground faults on pipes and cables. In the case of pipes, the faults consist of coating defects. In the case of cables, faults are usually caused by insulation damage allowing the metallic sheath (or internal conductor) to become in contact with the ground. It is intended to be used with the vLoc2 range of locators and will require a fault find signal applied to the faulty conductor from a Vivax-Metrotech compatible transmitter with fault finding mode. Carbon fiber reinforced glass fiber construction Plug-in-Play powered by receiver Forward/backward arrows point to fault
Vehicle Charging Lead The 12V vehicle charging lead will charge a locator’s Li-Ion rechargeable battery pack from an automotive cigarette lighter socket. This 12ft/4m lead makes it easy to stay charged up while on the go.
Ground Extension Spool Use the extension spool to extend the ground connection to reach a suitable grounding position. Extending the ground allows the user to move the ground lead to various positions to help the transmitters signal to travel further. By extending the length of the ground lead the user can use locate tactics such as performing a double ended connection.
