LABORATORY GAS DENSITY ANALYZER Russian patent published in 2019 - IPC G01N9/00 

FIELD: laboratory equipment.

SUBSTANCE: invention relates to analytical laboratory equipment, namely gas density analyzers. Laboratory gas density analyzer consists of a turbulent choke, the inlet of which is connected via a tee to the outlet of a chamber for compressing gases, made in the form of a spiral of a thin-walled metal tube and placed in a container with a coolant, and the input of the measuring chamber of the pressure sensor, as well as a pneumotumbler, connected to the output of a turbulent choke, and is distinguished by the fact that it additionally contains a microcompressor with an electric drive, an analog-digital converter and two additional pneumotumblers, the input of the microcompressor is connected to the input of the analyzer, and its output through one of the additional pneumoswitch is connected to the inlet of the chamber for compressing gases, the second additional pneumotumbler is connected to the output of the measuring chamber of the pressure sensor, the output of which is connected to the analog-digital converter, the electric drive of the microcompressor and the analog-to-digital converter are adapted to be connected to a computer.

EFFECT: higher accuracy of measuring the gas density.
