Electric isokinetic crude oil sampling for accurate composite samples without pneumatic or hydraulic drive requirements
The Welker inFlow™ Electric Crude Oil Sampler is an electrically actuated liquid sampler designed for accurate, representative composite sampling of crude oil, condensate, and other liquid hydrocarbons from flowing pipelines. Built for main line isokinetic sampling in custody transfer, meter run, and LACT unit applications, the inFlow™ Electric uses a volume-eliminating probe shaft to support real-time sampling while reducing residual sample retention. With AC and DC power options, a sloped probe shaft for complete BS&W drainage, a single-seal collection head, sturdy motor connections, and an air purge loop, this low-maintenance crude oil sampler delivers dependable performance in both standard and remote pipeline environments.
Main Line Liquid Hydrocarbon Sampling
Isokinetic composite sampling of crude oil, condensate, and other liquid hydrocarbons in flowing pipelines.
Custody Transfer and Meter Runs
Designed for accurate crude oil sampling in custody transfer, meter run, and LACT unit applications.
Remote or Electric-Only Locations
Supports pipeline sampling where AC or DC electric actuation is preferred over pneumatic or hydraulic power
Volume-Eliminating Probe Shaft
Helps deliver real-time, representative sampling by reducing residual volume inside the probe.
Single-Seal Collection Head
Simplifies maintenance and helps reduce downtime, repair time, and operating costs.
Electric Actuation With AC and DC Options
Provides flexible power options for standard facilities, remote installations, and low-voltage DC applications.
Sturdy Motor Connection
Supports reliable operation on high-vibration pipelines where sampler durability is critical.
Sloped Probe Shaft Design
Promotes complete drainage of basic sediment and water, or BS&W, to help protect sample accuracy.
Small-Diameter Probe Shaft
Fits smaller pipeline connections, expanding installation flexibility across crude oil and liquid hydrocarbon applications.
Air Purge Loop
Helps remove trapped air to improve sample volume accuracy and measurement consistency.
