The GPSD is designed specifically for small diameter 2″ or 3″ pipelines. The GPSD uses proven Genie® Membrane Technology to extract a representative gas sample and provide a safety net for protecting gas analyzers against liquid damage. This model’s housing is designed to install in a depressurized line.

Once installed, the housing includes a foot valve in its base, so the probe can be inserted or retracted with a pressurized line or vessel. The GPSD replaces the threaded foot valve (-T) housing option of the GPR.
