摘要： To provide a calibration device reliably accomplish communication filling without a great deal of labor when filling gaseous fuel (e.g., hydrogen gas) from a filling apparatus (e.g., a hydrogen filling apparatus) to a device to be filled (e.g., a hydrogen tank of an FCV) via the calibration device, and so on. A calibration device 100 according to the present invention includes a flowmeter 1; a filling nozzle 2 connected to the flowmeter 1 through a pipe 4A, the filling nozzle 2 having a communication input part 2A that receives information from a side 30 to be filled as an optical signal; and a receptacle 3 connected to the flowmeter 1 through a pipe 4B, the receptacle 3 having a communication output part 3A that outputs the signal received from the communication input part 2A of the filling nozzle 2 to a filling nozzle side of a filling device 20 that fills gaseous fuel, wherein the communication output part 3A is movable in a central axis direction of the pipe 4B connected to the receptacle 3, and an optical signal is emitted from the communication output part 3A toward the central axis of the pipe 4B.

摘要： To provide a gas filling apparatus with high handleability and safety. A gas filling apparatus including: a filling mechanism for carrying a gas through gas carrying pipes while measuring flow rate of the gas from a gas supply source (accumulator); a filling hose connected to the gas carrying pipe and having a filling nozzle at an end of the filling hose; and an attachment sensor (nozzle attachment detecting portion) for outputting a detection signal after detecting that the filling nozzle is attached to a filling port of an in-vehicle tank, wherein filling gas to the in-vehicle tank by the filling mechanism becomes possible after the detection signal is inputted to the filling mechanism from the attachment sensor. The gas filling apparatus may further include: a pressure gauge for measuring a pressure in the in-vehicle tank; a thermometer for measuring ambient temperature; and a target pressure calculating means (comparing means) for calculating a pressure in the in-vehicle tank when filling up the in-vehicle tank or filling preset amount of the gas is finished before filling gas to the in-vehicle tank based on a capacity of the in-vehicle tank and the measured pressure in the in-vehicle tank and the measured ambient temperature; wherein the filling mechanism stops carrying the gas to the in-vehicle tank when the pressure in the in-vehicle tank reaches the target pressure.
