To provide a gas meter capable of determining abnormal tilt of the gas meter after the gas meter has been installed.SOLUTION: A gas meter 10 includes: a shut-off valve 1; flow rate measuring means 3; a seismic sensor 2; and control means 6. The control means 6 is configured to have an acceleration value of the seismic sensor at the shipping stage in the gas meter manufacturing process as a first offset value and an acceleration value of the seismic sensor at the installation stage when installing the gas meter as a second offset value, and calculate a difference value A with the first offset value when the second offset value is acquired, and when the difference value A is greater than or equal to a specified value, to determine as abnormal tilt.SELECTED DRAWING: Figure 1 【課題】ガスメータ設置時以降に、ガスメータの傾き異常を判定するガスメータを提供する。【解決手段】遮断弁１と、流量計測手段３と、感震センサ２と、制御手段６とを備えたガスメータ１０であって、制御手段６は、ガスメータ製造工程における出荷段階の感震センサの加速度値を第１オフセット値とし、ガスメータ設置時における設置段階の感震センサの加速度値を第２オフセット値とて、第２オフセット値を取得した時点で、第１オフセット値との差分値Ａを算出し、差分値Ａが所定値以上の場合に傾き異常と判定する。【選択図】図１
