Abstract
A control method of a filled water volume in a fluid space requiring a water filling test is disclosed. The method includes disposing a pipe in the fluid space and enclosing the pipe with an enclosure, detecting pressure of a water filled portion in the fluid space or outside of the enclosure, and controlling the volumes of filling fluid and water to a water filling portion in the fluid space inside and outside the enclosure based on the detected pressure such that the pressure in the enclosure becomes higher than the pressure at the water filling part in the fluid space outside the enclosure.
