vLocDM2 Pipe Defect Mapper System
Defective pipeline coating and shorts to other structures can render cathodic protection ineffective. The vLocDM2 Pipeline Defect Mapper by Vivax-Metrotech has been specifically designed for surveying pipelines for these problems. And when not being used as a Current Mapper, the bottom magnetometer foot can easily be detached and the vLocDM2 becomes a fully-featured lightweight pipe & cable locator.

vLocDM2 A-Frame Screen
The A-Frame screen provides users the ability to view in real-time and pinpoint exact locations of pipeline coating defects and ACVG activity. Also displayed is a live plot of voltage gradient to assist users with identification of coating defects. In addition to directional arrow (points toward coating defect) is a peak locating graph with left/right guidance arrows and pipeline orientation indicator for simultaneous accurate pipe locating. Built-in (GPS) allows for exact location for further investigation and excavation.

vLocDM2 Measurement Screen
Taking a measurement is simple and fast. This screen displays the CURRENT DIRECTION ARROW and pipeline current, signal current, depth of pipe, distance from last measurement and which PCM signal being used.

Also when taking a measurement the completion bar at the bottom will give a time reference to the user.

vLocDM2 Graphing Screen
The graphing screen provides an instantaneous view and live plot of current attenuation on pipeline. This provides users with an instant diagnoses of pipe coating defects and areas of concern. Also, by scrolling plotted graph to where a known area of concern is indicated, user can then walk back (using built-in GPS) to exact location for further investigation (ACVG) for pinpointing coating defect, or locate for short detection, etc.

The vLocDM2 Receiver is a hand-held unit which is used to locate the pipeline and provide the operator with a measurement of depth, current magnitude and direction of the near DC signal as applied by the vLocDM transmitter and distance between logs.

The DM2 receiver makes the required calculations and displays the results automatically. The current measurement can be stored by a single button press in its internal memory and integrated with precise GPS longitude and latitude coordinates or sent to an external GPS device via its Bluetooth link (or direct cable link) for post-job analysis. Also this information is displayed live in real-time via built-in graphing screen.

The built-in GPS also provides for a unique walk-back feature, enabling users the ability to walk back to the area of concern for instant analysis. Older models required multiple crew visits, perhaps over multiple days to review and investigate data. These unique Vivax-Metrotech features provide operators with a method that quickly troubleshoots the CP system by pinpointing metallic contacts (shorts) and pin-pointing coating defects while still on the job-site, saving operators time and money and reducing time on the job site.

Real-Time graphing and GPS walk-back feature provides instant on-site analysis of pipeline current attenuation. This feature alone provides a revolutionary technological time saver for corrosion personnel utilizing PCM tools.

FULLY FEATURED PIPE LOCATOR - Additional cable locate modes and over 70+ available frequencies also allow the unit to be used as a traditional fully-featured cable and pipe locator and be used with most other manufacturers portable transmitters.

The vLocDM Transmitter is a high-powered unit which makes long range signal detection possible up to 20 miles (32km). The flexible power requirements enable it to utilize the variety of supplies available at most transformer rectifier stations. This allows the transmitter to provide its full 150W of output power over prolonged periods, without costly battery replacements. Hookup is a simple four wire connection procedure. The transmitter is compatible with both distribution and transmission networks.

NOTE: For extreme deep or long distance pipe locating the vLocDM transmitter can be selected for single frequency use (98Hz, 128Hz, 512Hz or 640Hz) providing up to 4.0 Amp of locating current output. Models vLocPro2, vLocML2, and vLocDM2 receivers can be used for this application.

Loc-150-Tx transmitter includes: 10' lead set, 10' DC input leads, 9' output mains plug.

DM A-Frame accessory provides for pinpointing of the coating defects to within a few inches. The A-Frame allows for ACVG and is automatic plug-n-play. The A-Frame accessory is constructed of lightweight carbon-fiber providing operator extended use. When using optional GPS, ACVG measurements can be taken and marked, and all coating defects can be easily located and marked for excavation crews.
