Purge trapped liquid from automatic samplers to protect sample accuracy between batches
The Welker Plug & Purge™ Automatic Purging System is designed for automatic liquid sampling systems that require reliable sampler purging in accordance with API 8.2 and ASTM D4177 recommendations. Engineered to safely and effectively purge trapped liquid product from the sampler to the sample container, Plug & Purge™ helps prevent sample carryover, cross-contamination, and water retention that can skew batch sampling results. With a Welker Purge Cylinder, remote valve actuator, regulator with safety relief valve, modular mounting options, and optional pressure transmitter for PLC monitoring, Plug & Purge™ supports accurate, repeatable crude oil and liquid hydrocarbon sampling system performance.
