MyLocator2
New with the vLoc series 2 - the MyLocator2 Configuration Management is a free desktop utility that
can be downloaded from www.vivax-metrotech.com.
The main features of interest to the vLocDM2 user are:
• Easy & quick upload facility for transferring data stored in the internal memory (files can be
exported includes .xls, .txt, .kml, .shp)
• Checking & downloading software updates for locator and/or MyLocator2
• Startup screen customization - add a picture or message that will show every time the locator
is switched on
Pipeline Defect Mapper
The vLocDM2 Transmitter
• The vLocDM2 transmitter can be powered by a Cathodic Protection station's external AC power (100V AC to 240V AC) or by a
12V DC - 60V DC source (power output is limited when powered by 12V DC).
• One of the output cables from the transmitter is connected to the pipe, the other to ground (see diagram A for transmission
pipes, diagram B for distribution pipes). The leads to the CP station are disconnected for the duration of the survey.
• A near DC signal is then applied by the transmitter for defect detection and a higher frequency is used simultaneously to locate
the pipe. The current flows at both frequencies and reduces noticeably where pipe coating is damaged.
One of the biggest threats to distribution networks is damaged or degraded insulation flanges. If the insulator fails , it compromises
the effectiveness of Cathodic Protection. It is essential that such failures are identified at the earliest opportunity if the CP is to be
returned to an effective level. The vLocDM2 Transmitter is applied to the network at a convenient point. The low frequency (3 or 4Hz)
is unaffected by well insulated joints, but the signal reduces sharply at damaged joints. To find a badly insulated joint, simply use the
vLocDM2 receiver to track the loss of current from the pipe.
