Abstract
PURPOSE: To measure the internal volume promptly and easily, by calculating according to the specified formula by detecting the pressure and temperature changes when a container of known pressure and volume is attached to the object being measured.
CONSTITUTION: By opening and closing valves 5a, 5c, 5b, a container 1 of known volume Vo is decompresses by a vaccum pump 2 or the like. By closing the valve 5b, the pressure and temperature, P1, T1, of the gas in the container 1 are measured by a pressure gauge 3 and a thermometer 4. Next, by opening the valve 5a, the container 1 is communicated with the object being measured 7 which accommodates a gas at pressure Po and temperature To. The pressure P2 and the temperature T2 after such communicating are similarly measured. Then, according to equation I, the volume Vx of the object being measured 7 may be easily measured. Hence, by averaging the measurements taken repeatedly, the volume may be measured at high precision.
