n: a device that, when installed in a pipe or flow channel and actuated by automatic control equipment. enables a representative sample to be obtained of the fluid flowing therein. systematic basis, which can be tested to determine the quality of the liquid flowing in the line. An automatic sampling device consists of a probe inserted into the line, an extractor, a timer or other device that controls the sampling rate, and a small tank (sample receiver) that holds the samples.

n: a representative sample taken from any suitable JX>int in a tank. or from a tank side sample connection after mixing the tank contents and before any significant separation of phases bas occurred.

n: a secondary pipeline circuit designed for quickly transferring product sample. This arrangement enables a representative sample passing through the main pipeline to be brought quickly to the sampling equipment, which may be located some distance from the main pipeline.

n: a small portion extracted from the total volume of material that contains the same proportions of the various flowing constituents as the total volume of liquid being transferred. The precision of extraction must be equal to or better than the method used to analyze the sample.

n: the extraction, conditions, transferring, and transporting of a representative sample from a container to analytical glassware or centrifuge tubes.

n: 1. the taking of a representative sample of fluid from a tank or pipeline to measure its temperature, specific gravity, and S&W content. 2. the process of cutting a core or pieces of core for analysis.

n: the mixing of pipeline contents, upstream of the sampling location, that is necessary for delivery of a representative sample.
