FIELD: the invention may be used for selection of samples of liquid from a pre-assigned depth of a technological capacity, a natural reservoir in oil producing, petrochemical industries, in depots for storage of oil products and for ecological control of surface sources of water.
SUBSTANCE: the arrangement for selection of deep-laid samples of liquid has a hollow chamber, a valve for accession of liquid and a cable for lowering of the chamber. A non-return valve of the plate type is located in the lower part of the chamber. The upper part of the chamber is connected in-series through a flexible armored hose with a pressure gauge, a gas meter, a three-way cock and a balloon with compressed inert gas. The arrangement allows control over the process of filling of the chamber with selected sample of liquid from a pre-assigned depth.
EFFECT: allows reduce unproductive expenses.
