  • No intrusion to the pipe and compact design means easy and safe installation and minimal maintenance.
  • Detectors indicate the amount of pipeline debris pushed ahead by a cleaning PIG, providing more information on the pipeline and greater integrity.
  • ROV retrievable and Non-retrievable options available for added flexibility.
  • No process wetted parts for lower installation and maintenance costs.
  • Detectors come mounted in fixed pre-installed clamp assemblies for simplified installation and retrieval.
