PROBLEM TO BE SOLVED: To shorten a time for measuring a pressure when the volume of a filled tank is provided. SOLUTION: A mass flowmeter 20, a gas supply open/close valve 22, a control valve 24, and a pressure transfer device 26 are disposed in the gas supply passage 18 of a dispenser unit 16. A control circuit 40 supplies a gas of a predetermined pressure to a gas supply route 18 by closing a three-way valve 30 and opening the gas supply open/close valve 22 and the control valve 24 before the supply of the gas is started in such a state that the downstream side end part of the gas supply passage 18 is connected to a fuel tank 14 side. Further, the control circuit 40 supplies the gas in the gas supply passage 18 to a fuel tank 14 by closing the gas supply open/close valve 22 and opening the three-way valve 30 in such a state that the gas of a predetermined pressure is supplied to the gas supply passage 18, and stores a pressure value measured by the pressure transfer device 26. The control circuit 40 supplies the gas to the fuel tank 14 according to a control rule based on the pressure value stored therein. COPYRIGHT: (C)2007,JPO&INPIT
