A+ Corporation Genie GPSD Membrane Small Diameter Probe

 The liquid is the root of many problems when sampling natural gas, either by its condensing out of the sample gas after entering the sample system or carrying it over from the pipeline into the probe. The entrained liquid is not always easy to locate.

Sometimes it cannot be detected by sight, but, instead, by its impact on analysis or damage to an analyzer. With Genie GPSD Membrane Small Diameter Probe, a Genie® membrane is inserted directly into a pipeline or vessel which allows for separation of entrained liquids at the prevailing line pressure and temperature conditions.

By separating entrained liquids at line pressure and temperature, sample integrity is maintained. Genie GPSD Membrane Small Diameter Probealso removes all entrained liquids in a gas sample, making them the most effective filters on the market for protection against liquid damage during upset conditions.





The Genie GPSD Membrane Small Diameter Probe is designed specifically for small diameter 2” or 3” pipelines. The Genie GPSD Membrane Small Diameter Probe 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 Genie GPSD Membrane Small Diameter Probe replaces the threaded foot valve (-T) housing option of the GPR™.

The liquid can be forced through any phase separation membrane when the flow rate through the membrane is too high resulting in excessive differential pressure across the membrane. Opening a ball valve downstream of the membrane to purge a sample cylinder during spot or composite sampling can cause this condition to occur.

To safeguard against this excessive differential pressure, we offer an optional flow restrictor that limits the flow through the membrane so as not to exceed a 2 psig drop thus preventing liquids from being forced through the membrane.

The flow restrictor should be selected when a Genie GPSD Membrane Small Diameter Probe is used in spot and composite sampling applications. It is not necessary to use a flow restrictor when sampling from lines that have very low pressure or when there will be a constant flow through the probe.
