This closed-loop sampling system 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 GSP system or return to process. Samples are collected in durable, pressure-rated metal grab sampling cylinders that securely contain the sample, ensuring operator safety.
A grab sampling cylinder is essential for the system's operation and is included with each GSP. The system 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.
