VOLUME MEASURING INSTRUMENT IN MICROGRAVITY

摘要

PROBLEM TO BE SOLVED: To provide a volume measuring instrument which can be used in a closed space such as measuring a liquid in a placed on an orbit of artificial satellite as well as makes measurement possible in a state where there is no mixing of gas, liquid and solid. SOLUTION: The volume measuring instrument in microgravity of this invention is characterized in that the instrument to measure the volume of liquid or solid under microgravity connects two or more vessels with tube and provides inside the vessels a means to separate or fix gaseous phase, liquid phase and solid phase, as well as a pressure changing source and a pressure signal receiver, wherein the pressure changing source and the pressure changing signal receiver are connected to a signal analysis unit.
