IRA-4SS Automatic Insertion Instrument RegulatorFeatures!!!!!!!!!Patented Automatic Insertion Device allows insertion andremoval of the probe from a high pressure pipeline through afullopen isolation valve without pipeline shutdown (specify insertionlength).Provides a regulated sample supply to chromatographs, H Sanalyzers, gravitometers, calorimeters, moisture analyzers, andother on-line analyzing equipment.Diaphragm design for increased low pressure output sensitivity.Probe design inhibits carry-over of free liquids into instrumentsupply system.Thermal fins on probe offset temperature change at point ofregulation and provide sample conditioning.316 stainless steel construction.Manufactured under U.S. Patent #4,346,611.Oil pot for smooth and safe insertion and retraction.Range springs available for 0-25 psi (0-1.7 Bar), 0-50 psi (0-3.52Welker Probe Regulators are designed to provide your chromatograph, H S analyzer, thermtitrator,moisture analyzers, gravitometer, calorimeter, or other on-line gas analyzers with a properlyconditioned sample stream. These regulators are designed with the point of regulation near the tip ofthe probe in the flowing stream. The natural temperature drop that occurs at the point of regulation(Joule-Thomson effect) is offset by the thermal fins on the probe tip. When used with an isolationvalve, the IRA-4SS can be completely installed or removed without interrupting pipeline flow oroperations. The IRA-4SS is another designed toimprove the profitability of your company.2Welker Innovative and Patented ProductTYPICAL INSTALLATIONSample Conditioning SystemAnalyticalEquipment(Chromatograph)OutletGaugePortHighCapacityReliefPortLength tospecify withorderFull OpenIsolation Valve(O 1" Internal Min.)Probe tip should bein the center 1/3 ofthe pipeEngineering CompanyISO- 9001CertifiedSince1992P.O.
