The Model 701 is an adjustable length insertion probe that can be inserted / retracted into a pressurised line without the use of a special insertion device.
With Genie Probes & Probe Regulators, 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.
Genie Probes also remove 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 701 Spot Sampling Manifold is recommended when using the 701 to extract a spot sample as it ensures that the sample path, from the process valve to the cylinder inlet valve, is thoroughly purged.
The PIP Spot Sampling Manifold is recommended when using the PIP to extract a spot sample as it ensures that the sample path, from the process valve to the cylinder inlet valve, is thoroughly purged. 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® Membrane Probe™ is used in spot and composite sampling applications. It is not necessary to use a flow restrictor when sampling from lines that have a very low pressure or when there will be a constant flow through the probe.
