Gas sample cylinder

Sentry’s sample cylinder allows gas samples to be collected at pressure, assuring that the sample constituents that can change state with pressure reduction are not lost during sample collection. An example of this type of sample would be LPG or other two-phase fluids that could flash off sample constituents if the pressure was reduced.

Since the sample is a pressurised liquid that has a high vapour pressure, the sample cylinder assembly provides for a safe method of collection and transport as long as the maximum fill density meets regulatory requirements.

The samplers use male/female Quick Disconnect sets on the sampler and cylinder, a system that prevents damage to the connections and minimises the number of sample cylinders needed for the process.

Sentry’s tandem switching valve handle allows a highly repeatable sample to be collected, improving sample accuracy. It simplifies operation and sampling by replacing manual manipulation of multiple valves with two three-way valves that perform multiple functions at one time. The valve features a large, ergonomic handle and wide operating arc for easy operation.

The valves have encapsulated balls that eliminate dead volume in the valve itself, preventing sample-to-sample contamination.

Options include sample coolers; sight glass/flow indicators; isolation valves; enclosures; pipe stands, purges and carbon canisters; higher-pressure ratings; filters; and special sampler materials.
