CD47-C Above Ground Marker (AGM)


The CD47-C with CDI's optional satellite radio can now send emails, text messages and Google Maps location of each pig passage to your Smartphone!


• The CD47-C Time-Based Benchmarker

• Detects transmitter equipped tools or MFL tools without transmitters

• GPS standard in every system

• Bluetooth downloading without cables

• Wide temp graphics LCD display

• Custom ABS plastic with urethane bumpers

• -40C to +85C operating temperature

• Swamp antenna options

• Subsea ROV/Diver housing available to depths of 150m (492 feet)


The CD47-C time-based benchmarker is designed to record within just a few milliseconds the GPS time of a passing intelligent inspection tool.  This precise time coupled with the physical pipeline location is correlated with the data recorded by the inspection tool. This correlated data provides a major increase in the accuracy of a smart pig's feature location callouts.


Utilizing precision time synchronization provided by its onboard Global Positioning System (GPS), the CD47-C is able to provide tool passage time accuracy that is guaranteed to be within 250 milliseconds over the 7 day battery life.


The CD47-C is the third generation time-based benchmarker created by CDI in response to customer's demands for an accurate, reliable, and robust piece of equipment that could be transported anywhere in the world and work right out of the box in the most extreme conditions of heat and cold. The CD47-C is smaller, lighter and simpler than the previous generations while providing greater ease of use.


With its ability to record passages of both transmitter-equipped and magnetic (MFL) inspection tools without transmitters, the CD47-C provides users with a comprehensive, well-tested and field hardened system for their benchmarking requirements.


The CD47-C is custom molded ABF plastic with urethane protective bumpers. Power to the system is provided by two D-Cell alkaline batteries which give a seven day operational life.


The LCD display on the face of the CD47-C provides the operator with immediate access to information about his pig run in any one of three languages: English, Spanish, or German.


Some of the information stored for every pig passage:

  • • GPS time of most recent pig passage
  • • Current GPS position including altitude
  • • Number of recorded passages
  • • Number of ignored magnetic events
  • • Firmware versions
  • • Precise GPS time of passage
  • • Battery Voltages
  • • Temperatures
  • • Fimware versions of CD47-C and GPS receiver
  • • Number and times/dates of any discarded magnetic disturbances
  • • Signal and Noise thresholds
  • • CD47-C serial number


LineStat email and text notifications

CD47-C with optional satellite radio for worldwide global service of automatic pig passage status reporting by email and text message with viewing passage locations in Google Maps. This is your best option for remote onshore locations to offshore platform work as cellular signals are not reliable or even available. This solution works anywhere in the world and relies upon the Globalstar network of earth orbit satellites.  No cellular access is required for LineStat to function.


CDI's SR100 satellite radios are ATEX and Class 1 Div 1 rated and are designed for field use.  These devices are rugged and built to withstand virtually any outdoor temperature extremes.

Marker Data Analysis Software

Using CDI's "Marker" program on a Windows computer, data analysis personnel can download and review the data recorded by the CD47-C benchmarking system and generate fully customizable reports in ASCII text or Microsoft Excel formats (CSV).  Report generation can be custom tailored by individual users with a built-in report configurator allowing automatic import of benchmarking data to a given company's proprietary inspection tool software.
