inFlow™ Crude Oil Sampler

With a forty-year track record of accurate, reliable, and repeatable results, the Welker inFlow™ Crude Oil Sampler is the sample extractor for most main line sampling applications. Inserted into the center one-third of your conditioned pipeline, the inFlow™ collects isokinetic samples of condensate, crude oil, and other liquid hydrocarbons. With an adjustable insertion length, optional automatic insertion, and four collection heads to choose from, there’s an inFlow™ poised to take advantage of your process conditions.

Capture set volumes of sample with the Vanishing Chamber™ collection cup. Each actuation of the sample pump voids the collection cup, fully displacing the sample into the connected sample container.

Does your application involve extreme temperatures, high pressures, or chemical contaminants? The B-Style collection head is up to the challenge! Even under such harsh conditions, this piston-style collection head fully displaces fixed volumes of sample into the connected sample container.

A companion to the collection head, the inline relief protects sample representativeness during fluctuations in pipeline pressure. Acting as a check valve, the inline relief keeps your samples in the sample container. If pipeline pressure drops, rest assured sample won’t flow from your container back to the pipeline. With the optional sand reliefs, you can sample product containing basic sediment and water (BS&W) without putting extra wear and tear on your sampler.
