It is wellknown that the gas oscillation appears in a tube whose one end is immersed in liquid He, and the other is closed at room temperature. A novel application of this oscillation is developed to increase the internal pressure in the He storage vessel. The apparatus includes a level meter to measure the liquid content, based on the same principle. Using the apparatus, the internal pressure can be controlled only by the valve operation. Moreover the liquid level can be measured even under the pressurized state.
