FIELD: measurement equipment.
SUBSTANCE: invention relates to versions of device arrangement for sampling of liquid media transported along a discharge pipeline. The device comprises a body, and also a piston installed in the body as capable of displacement, which separates the inner cavity of the body into two chambers. The piston is adapted for sampling the specified quantity of single samples in a sampler. The device comprises pipelines and stop elements to form a system of hydraulic lines that connect the body with a discharge pipeline and a sampler. At the same time the system of hydraulic lines has a section arranged in the form of a bypass line adapted for continuous passage of a liquid medium flow from a discharge pipeline during sampling of the specified quantity of single samples. Besides, the first chamber by means of the first hydraulic line with a valve installed on it is connected to the bypass line, and the second chamber by means of the second hydraulic line is connected to the sampler's input. Also the second chamber by means of the third hydraulic line is connected to a bypass line. The device may additionally contain at least one cabinet, through the wall of which at least one of pipelines is pulled, and such pipelines are designed to form a system of hydraulic lines.
EFFECT: provision of high extent of integrity of a sample composition with simultaneous simplification of a device and increased convenience of operation.
