Zusammenfassung:	A gas meter system includes a gas meter, a gas production plant, and a center device. The gas meter includes a sound velocity derivation unit configured to derive a sound velocity of a gas supplied to a demand place. The gas production plant includes: a gas production unit configured to produce the gas; and a gas characteristic identification unit configured to identify a gas characteristic representing a relationship between the sound velocity and a heating value of the gas based on an analysis result of a component of the gas produced by the gas production unit. The center device includes a gas heating value derivation unit configured to derive the heating value of the gas passing through the gas meter based on the derived sound velocity of the gas, and on the gas characteristic identified by the gas characteristic identification unit of the gas production plant.
