Economical composite sampling for low-volume NGL and light liquid streams
The Welker Essentials™ Light Liquid Sampler is a compact, double-acting positive displacement pump designed for representative composite sampling of low-volume natural gas liquid streams. Built for flow-proportional light liquid sampling in natural gas plants, refineries, and custody transfer applications, this bypass sample pump connects with a solenoid, pneumatic supply, controller signal, and constant pressure cylinder with internal mixer to create a complete liquid sampling system. With a compact footprint, probe-mounted isolation valves, economical design, and direct sampling from the flowing product, the Essentials™ Light Liquid Sampler supports accurate composition analysis and quality control.
Low-Volume Light Liquid Sampling
Composite sampling of low-volume natural gas liquid streams from approximately 100–4000 bbl/d.
Natural Gas Plants and Refineries
Light liquid sampling for composition analysis, quality control, and backup sampling when online analyzers are unavailable.
Custody Transfer Applications
Flow-proportional composite sampling where accurate representative samples are required for measurement confidence.
Resources
Representative Composite Sampling
Samples directly from flowing product to help deliver accurate, representative light liquid samples.
Probe-Mounted With Isolation Valves
Allows maintenance without interrupting flow, helping reduce downtime in plant and refinery operations.
Compact Footprint
Saves space in tight sampling system installations.
Economical Design
Provides a cost-effective sampling option for low-volume NGL and light liquid applications.
Positive Displacement Pump
Supports repeatable sample collection proportional to flow for composition analysis, quality control, and custody transfer.
