The GENIE 755™ sampling probe is an adjustable length, membrane tip probe regulator designed to sample transmission
quality natural gas. The pressure regulator is built into the probe immediately downstream of the
membrane, inside of the pipeline. Heat is transferred from the flowing pipeline gas to the regulator to
prevent excessive Joule-Thomson cooling, helping to prevent condensation during pressure letdown.
This model can be inserted and extracted from a pressurized line through a full opening valve without the
use of a special insertion device. It is important to note that some applications will require additional heat
to be applied before pressure regulation, and possibly multiple stages of pressure reduction. Contact us
for assistance in determining heating and pressure regulation requirements.
Liquid carryover from the pipeline into the sample system should be prevented when sampling natural
gas as it can directly impact the analysis and damage the analyzer. Genie® Probes™ provide a means
to insert Genie ® Membrane Technology ™ directly into a pipeline for the purpose of separating unwanted
liquid and particulate from the gas sample at flowing conditions; in compliance with industry standards.
Applications
• Continuous gas sampling and pressure regulation of transmission quality natural gas and various types of refinery and petrochemical gases
• Gas sampling of mixtures containing less than 30% hydrogen
Benefits
• Protection of the sample system from liquid and particulate contaminants while maintaining sample integrity
• Flowing pipeline gas helps to offset temperature changes at regulation point
