Fixed-insertion isokinetic sampling for small main lines, bypass lines, and LACT units
The Welker inFlow™ Fixed Crude Oil Extractor is a fixed-insertion liquid hydrocarbon sampler designed for bypass or main line isokinetic composite sampling of crude oil, condensate, and other liquid hydrocarbons. Sized for 2–4 inch sample lines, small main lines, separator outlets, and Lease Automatic Custody Transfer, or LACT units, the inFlow™ Fixed reaches the center one-third of the pipeline to support representative sample collection via direct-mount or with a pipe spool. With fixed or adjustable positive displacement collection heads, a double-acting piston motor, Welker Volume Eliminator, inline relief, optional pipe spool with static mixer, optional sand reliefs, and optional Welker Purge Tube, this compact crude oil sampler helps improve sample accuracy for truck loading, rail car loading, and liquid hydrocarbon transfer applications.
Small Line Liquid Hydrocarbon Sampling
Bypass or main line isokinetic composite sampling of crude oil, condensate, and other liquid hydrocarbons on 2–4 inch lines.
Separator Outlet Sampling
Designed for representative sampling downstream of a separator where compact fixed insertion is preferred.
LACT Unit Sampling
Supports crude oil sampling on Lease Automatic Custody Transfer units for truck and rail car loading and unloading.
