PROBLEM TO BE SOLVED: To provide a gas meter device with which it is possible to appropriately evaluate the deformation state at each floor of a building by calculating an interlayer deformation angle and improve a safety function in gas supply.SOLUTION: A gas meter device 1, provided at each floor of a building 10, comprises a control unit 11, an input unit 12, a display unit 13, an acceleration sensor 14, a shutoff valve 15, a pressure sensor 16, a flow rate sensor 17, and an interface unit 18. The gas meter device 1 measures, by the acceleration sensor 14, acceleration at a floor where the acceleration sensor is installed, calculates a horizontal deformation at the installed floor that is obtained from the acceleration and an interlayer deformation angle at the installed floor by using the height of the installed floor, and, when the interlayer deformation angle exceeds a threshold, closes the shutoff valve 15 to shut off the gas supply. |
