FIELD: measuring technique.
SUBSTANCE: device comprises valving device mounted between the horizontal first pipeline and second pipeline. The second pipeline whose sections are arranged above the first pipeline is provided with measuring section that is used as a measuring chamber. The first radioactive isotope means is used for measuring the mass of a portion of gas-containing liquid supplied to the chamber and has first unit of radiation source and first unit for detecting radiation arranged at the top and the bottom end of the measuring section, respectively. The axis of the measuring section is vertical or is inclined to the longitudinal axis of the first pipeline. The second radioactive isotope means is used for determining the presence of gas-containing liquid in the measuring section and has second unit of the radiation source, second unit of radiation detecting that are arranged in the top part of the measuring section from two diametrically opposite sides.
EFFECT: simplified design and reduced time of measuring.
