SOLUTION: A calculation part 50 of a gas meter includes a forward and reverse determination circuit 60, a flow rate calculation circuit 70, a memory part 80 and a display drive control circuit 90.

摘要： PROBLEM TO BE SOLVED: To eliminate a filling error due to lowering of pressure in a filling hose in gas filling.
SOLUTION: In this gas supply device 11, a fuel tank 12 is filled with gas, and after the end of filing when the flow measurement is ended, according to a detection signal from a coupler switch 65, a control valve 28 is opened to raise the interior of the filling hose to a designated pressure, so that when filling the fuel tank 13 of a vehicle with gas, the interior of the filling hose has been already increased in pressure. Accordingly, an error due to pressure rise in the filling hose 35 can be prevented, and also the wait time can be shortened. Since the interior of the filling hose is increased in pressure before a filling coupler 49 is connected to the fuel tank 13, when a worker connects the filling coupler 40 to the fuel tank 13 of the vehicle, vibration due to pressure fluctuation is not transmitted to the hand of the worker, so that the worker will not feel incompatibility.

摘要： PROBLEM TO BE SOLVED: To provide a gas supply device capable of reducing a period of time for filling gas.
SOLUTION: When the gas pressure of a fuel tank 12 is lower than a first gas pressure threshold valve (10 MPa), that is, when it is predicted that the temperature drastically rises corresponding to the filling of the hydrogen gas, a second pressure increase rate [5 MPa/min] is selected and the filling is controlled (step S12), whereby the drastic temperature rise is alleviated to proceed the gas filling. After the gas pressure of the fuel tank 12 reaches a pressure that exhibits a moderate temperature rise characteristics, the second pressure increase rate is changed to a first pressure increase rate (15 MPa/min) to control the filling (step S8). By the alleviation of the drastic temperature rise by selecting the second pressure increase rate, interruption of the filling caused by the temperature rise of the fuel tank 12 to its heat-resistant tolerance temperature can be avoided so as to surely continue the filling control. Also, by controlling the filling at the first pressure increase rate, it is possible to ensure the rapid filling and to shorten the period of the gas filling time.

摘要： PROBLEM TO BE SOLVED: To suppress the control dispersion of a trace flow amount due to the property of a control valve.
SOLUTION: A control device 16 makes a filling side coupler 46 mounted at the front end of a gas supply passage 18 in communication with a filled side coupler 12a of a filled tank and then opens the control valve 26 provided in the gas supply passage 18 to supply gas to a fuel tank 12, and computes a remaining filling amount (a filling possible amount) in the fuel tank 12 in accordance with a pressure value measured by a pressure sensor 30. It keeps the opening of the control valve 26 constant so that the gas to be supplied into the fuel tank 12 is kept at a predetermined trace flow amount when the pressure sensor 30 measures the pressure valve when supplying the gas into the fuel tank 12. Then, it controls the filling of the gas to be supplied into the fuel tank 12 in accordance with the computed filling possible amount in the fuel tank 12.
