Main line isokinetic composite sampling of condensate, crude oil, or other liquid hydrocarbons
All custody transfer applications
Transmission pipelines
High-speed sampling for short sample batches
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.
Fixed or adjustable volume positive displacement collection heads

Benefits
Pumping power capable of sampling high-viscosity products
Insert and retract the shaft under reduced or full pipeline pressure
Retractable shaft allows for pipeline pigging and inspection or equipment maintenance without costly shutdowns
Reach the center third of multiple pipeline diameters
Capture and fully push samples to the sample container
With adjustable collection heads, collect large grabs for small volume batches
Minimize sample retention and keep residual sample at a minimum
Inline relief prevents collected samples from flowing back to the pipeline if pipeline pressure drops
Sample products containing basic sediment and water (BS&W) without the extra wear and tear (optional)
Purge trapped liquid from the collection head to the sample container for a complete composite sample and to prevent batch cross-contamination (optional)
