High-speed inline composite sampling for NGLs, condensate, and refined light liquids
The Welker inFlow™ Lite is a double-acting inline sample pump designed for representative composite sampling of high-flow condensates, natural gas liquids, LPGs, gasoline, diesel, biodiesel, and light viscosity crude oil. Built for inline or bypass liquid sampling applications, the inFlow™ Lite samples proportional to flow and mounts directly to the pipeline with isolation valves for easier maintenance without removing the unit from service. With external sample volume adjustment, a self-cleaning filter, stainless steel wetted parts, cartridge check valves, and pneumatic or hydraulic actuation, the inFlow™ Lite helps operators collect accurate light liquid samples with minimal downtime.
Inline Light Liquid Sampling
Composite sampling of NGLs, LPGs, gasoline, diesel, biodiesel, condensate, and light viscosity crude oil directly from flowing pipelines.
Bypass Light Liquid Sampling
Composite sampling of NGLs, LPGs, gasoline, diesel, and biodiesel in bypass applications where sufficient flow is guaranteed.
BS&W Analysis Applications
Light viscosity crude oil and condensate sampling downstream of a static mixer for accurate BS&W analysis.
Complies With:
Representative Composite Sampling
Samples directly from flowing product to help collect accurate, representative composite samples.
Probe-Mounted With Isolation Valves
Allows sampler maintenance without removing the unit from the pipeline or interrupting flow.
Self-Cleaning Filter
Separates entrained particles or sediment from process fluid and can reduce the need for a separate upstream filter.
External Sample Volume Adjustment
Lets operators meet changing sample volume requirements without removing the sampler from the pipeline.
Double-Acting Pneumatic or Hydraulic Actuation
Supports high-speed service for demanding light liquid and refined product sampling applications.
Stainless Steel Wetted Parts
Provides corrosion resistance and durability for longer product life.
Cartridge Check Valves
Simplifies maintenance and supports reliable sample capture during repeated sampling cycles.
