Roxar™ PDS PIG Detection System
Roxar Pig detector
The Roxar PDS is an intelligent, non-intrusive device for detecting Pipeline Inspection Gauges (PIGs) in topside applications.
It detects and monitors the acoustic noise generated when PIGs pass the device in pipeline flows. The Roxar Pig Detector is non-intrusive, leading to easy and cost-effective installation and provides immediate information to the user for enhanced pipeline integrity.
