FIELD: oil and gas industry.
SUBSTANCE: invention relates to an improvement that provides high reliability of obtained measurements in the field of analyzing gas samples. Sampling system includes a sampling probe, a valve with a drive and a state detector. Detector is configured to generate at least one control signal transmitted to the drive to stop sampling from the pipeline at instability of the fluid flow.
EFFECT: invention provides detection of unstable conditions of flow in pipeline, stops analysis of fluid samples at instability of fluid flow and resumes sampling during recovery of steady state of flow.
