FIELD: transport.
SUBSTANCE: invention relates to space engineering. Working gas temperature and pressure are defined and gas weight residues are defined at every step before working gas portion extraction from the system gas tank in compliance with the ideal gas equation. Gas weight in constant-volume instrument vessel by pressure and temperature transducers. Working gas portion is extracted from the system vessel to constant-volume intake vessel. Extracted portion of working gas is transferred to common vessel for conversion of working gas into ideal gas. Gas volume in common vessel and unknown volume of working gas are defined by the formula of ideal gas state. Common vessel consists of intake and instrument vessels.
EFFECT: higher accuracy of gas residues determination.
