Guide to Representative Sampling
Learn the many benefits of representative sampling and get answers to your representative sampling questions
The Sentry manual inline sampler is an ideal oil and gas solution for sampling liquids in processes that require little interruption. The sampler can be used in refinery processes, chemical applications, petroleum sampling equipment and the nuclear industry.
This low-emission sampler limits exposure to the downstream oil and gas operator. It also assists in following environmental regulations and maximizing a representative sample.
The sampler's unique features include a close-coupled ball valve. This valve provides a low "dead volume" in the sample flow. A low dead volume ensures samples from flowing process lines are accurate at pressures up to 2200 psi (150 bar). Higher temperatures will require a lower pressure, however.
This direct liquid sampling equipment can sample liquids and light mixtures in pipes and process lines throughout petroleum sampling equipment, chemical applications and oil and gas processes. The variety of available connections, needle assembly, and bottle sizes allows consumers to customize the manual inline sampler to meet their application needs.
Alternatively, nuclear applications require a different approach. Sampling within nuclear power plant applications occurs in one of three locations:
The sampler does not reduce the inlet fluid pressure significantly, regardless of the application. Having a low-pressure drop allows you to operate at a lower inlet pressure. Additionally, no valve stems or other components pass through the sampler. This design ensures maximum safety in your oil and gas equipment.
