摘要： Provided is a gas meter system capable of deriving a heating value of a gas with high accuracy. A gas meter system (100) includes a gas meter (110), a gas production plant (114), and a center device (116). The gas meter (110) includes a sound velocity derivation unit configured to derive a sound velocity of a gas supplied to a demand place. The gas production plant (114) 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 (116) includes a gas heating value derivation unit configured to derive the heating value of the gas passing through the gas meter based on the sound velocity of the gas, which is derived by the sound velocity derivation unit of the gas meter, and on the gas characteristic identified by the gas characteristic identification unit of the gas production plant.

摘要： Provided are a gas meter system and a heating value estimation method that are capable of estimating a heating value of a gas with high accuracy. A gas meter system (100) is configured to: derive a heating value of a gas passing through a first gas meter (110); and estimate a heating value of a gas passing through a second gas meter (111) provided separately from the first gas meter (110) based on the heating value of the gas of the first gas meter (110) that is arranged within a predetermined range with respect to the second gas meter (111) on a gas supply pipe (130) configured to supply the gas.
