CAC – LNG Sampling System

THE WELKER LNG SAMPLING SYSTEM FACILITATES THE VAPORIZATION AND CONDITIONING OF A SAMPLE OF LNG FROM ITS LIQUID STATE TO A GASEOUS STATE IN COMPLIANCE WITH THE INTERNATIONAL STANDARDS FOR LNG SAMPLING

WELKER’S REVOLUTIONARY LNG DESIGN

While other LNG probes and systems rely on maintaining temperatures up to the vaporization stage, which could cause potential
compositional separation and fallout, the Welker LNG probe eliminates this possibility. The patented check valve design allows for small amounts
of LNG to enter the sample system at the probe tip and immediately begin the gasification process. This not only eliminates the possibility
of heavier components escaping the system and returning back into the process, it also greatly reduces the line pack and increases
measurement accuracy and timeliness of results. This patented check valve design is an innovation in LNG sampling application and is yet
another example of Welker products leading the way in the sampling industry.
