Pipeline Watchdog P2S

Induced AC Voltage Detection and Reliable CP Data Reporting

Click for larger image. The Pipeline Watchdog P2S is a new generation remote monitor that reliably monitors your pipeline CP test points and improves the integrity of your pipeline by providing regular pipe-to-soil data and alerting you to any loss of cathodic protection or to the presence of harmful induced AC voltages. It is also an excellent critical bond current monitor.

The unit is sealed for moisture protection. The installation requires simply connecting two wires and pushing a start switch. It is battery powered and self contained for field deployment wherever digital cellular coverage exists.


P2S Benefits

  • Automatically monitor and report pipe-to-soil potentials
  • Detect hazardous induced AC voltages.
    • Useful in areas with high voltage power lines, electric trains, etc.
  • Eliminate travel to sites to perform test point readings
  • Immediate alarming of:
    • High or low pipe-to-soil voltage
    • Out-of-tolerance or polarity critical bond current
    • Hazardous induced AC voltage
  • Simple data reports from the website. Quickly set up automated reports, in selectable format for easy import into popular CPDM software (Bass-Trigon, ProActive, Paradigm, .XLS, .CSV, .XML, etc.)
  • Low monthly messaging costs
