The Production Gas Sampling System (PGSS) provides a liquid-free, low pressure sample from natural gas streams for process control analysis. It extracts the sample using a direct-drive probe, removes liquids using a coalescing filter and membrane separator, and reduces pressure using a heated regulator without Joule-Thomson cooling effects. Optional heat tubing allows compatibility with low and high dew points. The PGSS mounts directly onto pipelines for accurate sampling close to wellheads.
