n: in tank sampling, a sample that is obtained by submerging a stoppered beaker or bottle to a poinias near as possible to the draw-off level, then opening the sampler and raising it at a rate that makes it about three-quarters full (maxi- mum 85%) as it emerges from the liquid.

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.

a tool that takes bottom hole samples of fluids or solids.

n: a sampler that automatically adjusts the quantity of sample in proportion to the rate of flow.

n: a sampler that transfers equal increments of oil from the pipeline to the sample container at a uniform rate.

n: 1. a small portion of a formation obtained by using a core bit in an existing wellbore. See core bit. 2. a spot sample of the contents of an oil or oil product storage tank usually obtained with a thief, or core sampler, at a given height in the tank.

n: The rock sample whose diameter is from 50mm to 100mm ,acquired from bottom hole when core drilling.

n: the tools used to get the samp of formation fluid and pressure one time respectively during both pressure-closing

n: a device that is operated by a power source other than the fluid being sampled, for example, an electric or pneumatic motor.
