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 deviceaccording to the present invention includes a flowmeter; a filling nozzleconnected to the flowmeterthrough a pipeA, the filling nozzlehaving a communication input partA that receives information from a sideto be filled as an optical signal; and a receptacleconnected to the flowmeterthrough a pipeB, the receptaclehaving a communication output partA that outputs the signal received from the communication input partA of the filling nozzleto a filling nozzle side of a filling devicethat fills gaseous fuel, wherein the communication output partA is movable in a central axis direction of the pipeB connected to the receptacle, and an optical signal is emitted from the communication output partA toward the central axis of the pipeB.

Receptacle, calibration device and filling apparatus

Provided is a beryllium copper alloy bonded body including a first member made of a beryllium copper alloy and a second member made of a beryllium copper alloy, wherein the first member and the second member are bonded to each other via the nickel layer having a thickness of 8 &#x3bc;m or less.

Beryllium copper alloy bonded body and production method therefor

To provide a calibration device for apparatus filling a gas such as hydrogen gas and capable of precisely measuring quantity of the gas such as hydrogen gas that are filled at high pressure. A calibration deviceaccording to the present invention includes a measurement housingaccommodating a filling vesselto which a high pressure fuel gas is fed from outside; a scalefor measuring a weight of a fuel gas fed to the filling vessel; and a main body housingaccommodating the measurement housingand the scale

Calibration apparatus

To provide a calibration device for apparatus filling a gas such as hydrogen gas and capable of precisely measuring quantity of the gas that is filled at high pressure. A calibration device of the present invention includes: a filling vessel, accommodated in a measurement housing, to the filling vessela high pressure fuel gas such as hydrogen gas being fed from outside of the measurement housing; a scalefor measuring a weight of a fuel gas fed to the filling vessel; and a control device CU for eliminating an error caused by changing buoyant force from a gas in the measurement housing before and after filling the fuel gas.

Calibration device and calibration method

To provide a calibration device for an apparatus filling a gas such as hydrogen gas and capable of precisely measuring quantity of the gas such as hydrogen gas that are filled at high pressure. A calibration device of the present invention is characterized by including a filling vessel, accommodated in a measurement housing, to the filling vessel a high pressure fuel gas such as hydrogen gas being fed from outside of the measurement housing, and a scale for measuring a weight of a fuel gas fed to the filling vessel, wherein a dry gas pipe for feeding a dry gas is detachably mounted in the measurement housing. Here, the scale preferably measures the weight of the fuel gas fed to the filling vessel together with a weight of the measurement housing.

Calibration device

To provide a calibration device for apparatus filling a gas such as hydrogen gas and capable of efficiently and safely measuring weight and amount of the gas such as hydrogen gas that are filled at high pressure. Calibration devicesaccording to the present invention include a measurement housing, accommodated in a housing main body, to the measurement housinga high pressure fuel gas being fed from outside of the housing main body; and a scalefor measuring a weight of a fuel gas fed to the measurement housing, wherein an inside of the measurement housingis visible from outside of the housing main body

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.
