Catalog excerpts

Real time pig detector for oil, gas or multiphase pipelines The Roxar subsea Pig detector is a bi-directional intelligent device that utilizes the acoustic energy generated by travelling pigs to calculate pig-passed signals for oil, gas or multiphase pipeline flows. The detector provides real-time information and provides an accurate registration of passing pigs. Roxar offers two models; ROV retrievable and Non-retrievable, both mounted in fixed pre-installed clamps assemblies.
