LABORATORY EFFICIENT ANALYZER OF GAS DENSITY Russian patent published in 2019 - IPC G01N9/00 G01N9/32 

FIELD: monitoring and measurement equipment.

SUBSTANCE: invention relates to analytical laboratory equipment, namely gas density analyzers. Stated laboratory effusion gas density analyzer, which contains turbulent choke 1, output 2 of which is connected to pneumotumbler 3, chamber for compressing gases 4, made in the form of a spiral of a thin-walled metal tube and placed in coolant tank 5, tee 6 and pressure sensor 7 with measuring chamber 8 provided with inlet 9 and outlet 10 with nozzles. According to the invention, the analyzer further comprises microcompressor 11 with electric drive 12, analog-to-digital converter 13, laminar choke 14, three additional pneumotumblers 15, 16 and 17 and one additional tee 18. Input 19 of microcompressor 11 is connected to input 20 of the analyzer, and its output 21 through one of additional pneumotransmitters 15 is connected to input 22 of chamber 4 for compressing gases. Tee 6 is connected to outlet 23 of chamber 4 for compressing gases, inlet 9 of measuring chamber 8 of pressure sensor 7 and the input of additional tee 18, the two outputs of which are connected to inlets 24 and 25 of turbulent 1 and laminar 14 chokes. Output of pressure sensor 7 is connected to the input of analog-digital converter 13, and second 16 and third 17 additional pneumotumblers are connected respectively to output 26 of laminar throttle 14 and outlet fitting 10 of measuring chamber 8 of pressure sensor 7. Actuator 12 of microcompressor 11 and analog-to-digital converter 13 are configured to be connected to a computer.

EFFECT: expanding the functionality of the device by allowing the analyzer to measure both the density and dynamic and kinematic viscosity of gases.
