Crude Oil Panels

WELKER > Crude Oil Panels


Confirm actual sample grab size from one convenient spot. A valuable addition to your liquid sampling system, the Welker Checkpoint™ Sample Bite Verification Panel makes sampler performance monitoring easy. A pressure switch and relief valve on the panel provide an additional layer of system protection.

Plug & Purge™

The first of its kind, the Welker Plug & Purge™ Automatic Purging System meets the latest recommendation of API 8.2 and ASTM D4177. Welker applied 25 years’ experience purging probe samplers to design the Plug & Purge™, which safely and effectively purges trapped liquid product from the sampler to the sample container. Incorporate the Plug & Purge™ into your automatic sampling system and increase your system’s accuracy.
