FIELD: oil and gas industry.
SUBSTANCE: crude oil investigation device (PVT) includes high pressure vessel of variable volume, which includes mixing device and measuring instruments recording working volume of vessel, temperature and pressure in it. Mixing device is equipped with magnetic mixer consisting of two annular magnets. At that, lower end of external magnetic ring - annular rotor is connected to folding spring mixer. Spring mixer has the shape of flat band spring along the diameter equal to inner diameter of vessel, which allows mixing the whole vessel volume at its rotation. At that, when plunger-piston is introduced to or taken from vessel, flat spring is folded or stretched. Inner magnetic ring - stator is made in the form of a sleeve with possibility of rotation about head of high pressure vessel housing from external drive.
EFFECT: improving reliability, quality and accuracy of measurements.
