FIELD: aircraft engineering.
SUBSTANCE: invention relates to spacecraft servicing and can be used in filling fluid heat control systems and spacecraft engines. This method uses reference tank 12 communicated via pipeline 5 with gas chamber 2 of controlled fluid 3 and incorporating "gas-fluid" separator 13. In measuring volumes of gas chamber 2 and reference vessel 12, volume of gas that passed through gas counter 11 is measured two times at different initial basic pressures. Results obtained allow determining nonsolute gas volume by appropriate formula. Note here that said initial basic pressures in gas chamber 2 and reference chamber 12 are set equal. In first measurement, said pressures make 1 mm Hg, while in second measurement they make 2 atm.
EFFECT: possibility to determine volume of nonsolute gas in fluid chamber 14 without its depressurisation and connection to filling appliances.
