A sample fluid stream can be received from a main fluid stream through a nozzle of a probe located at least partially in the main fluid stream. The sample fluid stream can travel into the nozzle and a portion of the main fluid stream adjacent to the sample fluid stream can flow past the probe without entering the probe. The sample fluid stream can flow downstream within the probe, and a portion of the main fluid stream can flow downstream outside the probe. While receiving the sample fluid stream, a gas sheet can be directed from the probe, with the gas sheet flowing upstream against the main fluid stream.

A system for on-stream sampling of pressurized process gas such as natural gas or the like, said pressurized process gas having liquid entrained therein, or otherwise referenced as wet. The preferred embodiment of the present invention contemplates a system for obtaining an accurate sample of said wet process gas, as well as providing an apparatus for obtaining same.
