The CD47-C time-based benchmaker 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 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.

Information provided on the LCD display during a run:

• GPS time of most recent pig passage
• Current GPS time
• Current GPS position
• Number of recorded passages
• Number of ignored magnetic events
• Firmware versions

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 reports in ASCII text or Microsoft Excel formats.  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.

Data stored per recording:

• Precice GPS time of passage
  
• GPS position and altitude
• Battery Voltage
• Temperature
• Fimware versions of CD47-C and GPS receiver
• Number of ignore magnetic events
• Signal and Noise thresholds
• CD47-C serial number
