LS-14

All-in-one light liquid sampling, mixing, and containment for multiple subsamples

The Welker LS-14 Light Liquid Sampling System is an all-in-one solution designed to collect, mix, and maintain a large-volume representative composite sample of light liquid products. Ideal for custody transfer, refined product analysis, and applications requiring multiple subsamples, the LS-14 combines a Welker sample pump, large-capacity constant pressure sample container, built-in push-button mixer, inert pre-charge gas supply tank, and optional Mod Skid™. By maintaining collected samples at pipeline condition and mixing before withdrawal and transport, the LS-14 supports accurate BS&W, Reid vapor pressure, octane, composition, and quality analysis.
