EMRx Subsea


  • Intuitive and easy to use - one control on the unit carries out all functions.
  • Digital Signal Processing (DSP) provides enhanced functionality, signal-to-noise ratio and frequency selectivity.
  • Has the potential to greatly reduce downtime, and therefore costs, by facilitating the process of locating a stalled pig or confirming if a pig has left the launcher or been successfully received.
  • The enhanced sensitivity permits the location of transmitters even within very heavy walled receivers/launchers, pipeline bundles or Pipe-in-Pipe
  • Detection through pipeline walls in excess of 40mm thick is possible dependent on transmitter settings and environmental factors.
  • Multi-frequency feature allows user to identify and locate individual pigs.
  • The EMRx software application allows simultaneous receipt of any number of frequencies between 10Hz and 30Hz.
