Liquified Gas Sample Panel

    REQUEST QUOTE   

The Vaporized Gas Sample Panel (LGSP) manufactured by Sigma Sampling Systems is a closed-loop system that draws fluid from a positive-pressure process and returns it to a lower-pressure location by using differential pressure to either circulate the fluid through the LGSP (sample position) or return it to process (bypass position). Samples are collected in durable, pressure-rated metal grab sampling cylinders that securely contain the sample, ensuring operator safety.

The LGSP can remain indefinitely in either the bypass or sample position, ensuring  transport lines remain fresh and prepared for sample collection. Optional features include a rupture disc for added safety, with an additional relief valve available for situations where overpressure is a concern.
