Abstract
Volume measuring apparatus is used in a closed space as in the case of volume measurement of liquid in a container placed on an orbit of an artificial satellite and permits the volume measurement in a state without mixture with gas, liquid, or solid. A volume measuring apparatus is an apparatus for measuring the volume of liquid or solid under microgravity, which has two or more containers coupled to each other by a pipe, a device for separating or fixing a gas phase, a liquid phase, or a solid phase, a pressure fluctuation source, a pressure signal receiver, a pressure gage, and a thermometer, wherein the separating or fixing device, the pressure fluctuation source, the pressure signal receiver, the pressure gage, and the thermometer are placed in the containers and wherein the pressure fluctuation source, the pressure signal receiver, the pressure gage, and the thermometer are connected to a signal analyzing unit.
