Two-stage liquid protection for natural gas analyzers
The Welker Guardian Analyzer Liquid Shutoff and Liquid Eliminator combines two-stage analyzer protection in one compact natural gas sample conditioning device. Installed upstream of an analyzer as a standalone component or part of a conditioning system, The Guardian removes liquids from gas samples and provides positive shutoff when liquid is present to help prevent contamination, equipment damage, and operational shutdowns. With a liquid-eliminating chamber, sight glass for visual flow confirmation, positive liquid shutoff, and stainless steel construction, The Guardian helps protect gas chromatographs and analyzers while simplifying installation and maintenance.
