The Welker Liquid Eliminator Filter Regulator is designed specifically for use with on-line analyzers. Installed properly in analyzer sample lines, these regulators effectively eliminate free liquids from entering gas analyzers. The LEFR-1 employs a membrane element to ensure that liquids are knocked out without affecting the natural gas flow. This membrane is located down stream from the point of regulation so that liquids caused by the Joule-Thomson effect are eliminated prior to flow into the heated tubing run. Design of the regulator places the outlet port well above the drain so that the gas sample passing through the element is not flowing through any accumulated liquids. The LEFR-1 is another Welker Original Product designed to improve the quality of your measurement sample
