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.
