PURPOSE: To simplify the device and reduce the price by providing a supply source of an ultracryogenic liquid and a pressure vessel of high withstand pressure, and transferring the liquid by a sufficient quantity so as to obtain gas of pressure close to the designed usable pressure of the pressure vessel, when the temperature in the pressure vessel becomes -17.8 deg.C. CONSTITUTION: A storage tank 11 receiving LNG existing only at ultracroygenic temperature, and a pressure vessel 13 to be filled with gas are provided, a heat insulating conduit 12 is connected between both, and correctly measured LNG by a meter 12 is transferred to the pressure vessel by a pump 16. The quantity of LNG to be transferred is computed so as to be the designed working pressure of the pressure vessel when the temperature in the pressure vessel becomes -17.8 deg.C. |
