Sample Smarter with the GSS-4! đ§
Sample Smarter with the GSS-4! đ§
Where to Use Composite Sampling of Natural Gas   No autographs, please. The unrivaled accuracy of Welkerâs GSS-4PM Gas Sampling System is world-famous. Its unparalleled decades-long history of representative sampling, repeatability, and accuracy have made the GSS-4PM the composite sampling system for natural gasâwet or dry, clean or dirty. Probe-mounted and self-purging, the GSS-4PM is a self-contained system compatible with single cavity and constant pressure cylinders. With the Vanishing Chamber⢠collection cup at the heart of the positive displacement pump, thereâs no doubt your samples will be as representative and accurate as the results of an online analyzer.

Where to Use As part of a seal support system for centrifugal and reciprocating compressors with dry gas seals Upstream of pneumatically actuated emergency shutdown valves Upstream of sensitive pneumatic instruments in remote locations     The Welker CleanFlow⢠F-31 Instrument Grade Gas Conditioning System is designed to provide a continuous supply of clean, dry gas to critical pneumatic instruments and industrial equipment. This simple, low maintenance system includes 2 or 4 of Welkerâs high-capacity F-31 Filter Dryers to accommodate high-pressure, high-flow gas streams. With a long service interval, these efficient filters maximize reliable operation.
LPG Composite Sampling System
LPG Composite Sampling System
Where to Use Sampling low-temperature hydrocarbons Loading and receiving terminal of a refinery    The LPG Composite Sampling System is a precision-engineered hydrocarbon liquid sampling system designed to safely capture representative samples of low-temperature hydrocarbons such as propane, ethane, butane, pentane, and refrigerants. Its rugged stainless steel construction and advanced circulation design ensure accurate sampling even under challenging low-pressure and low-flow conditions.

Where to Use Bypass or main line isokinetic composite sampling of crude oil, condensate, or other liquid hydrocarbons All custody transfer applications Transmission pipelines High-speed sampling for short sample batches Downstream of a separator On a Lease Automatic Custody Transfer (LACT) unit    Introducing the FLP Mini Fast Loop Sampler, designed for efficient, real-time sampling directly from pipelines. The FLP is designed to create a compact, isokinetic fast loop and collects a representative sample in real time. Ideal for crude oil transfer lines and large refined product, the probe offers easy retractability and automatic insertion. It integrates seamlessly with solenoid, pneumatic, or hydraulic valves, making it perfect for remote, solar-powered locations. With minimal maintenance required and easy access to the collection head, itâs an ideal solution for low-maintenance, remote environments.
