Abstract

A gas meter system is configured to: derive a unit heating value of a gas passing through a first gas meter; and estimate a heating value of a gas passing through a second gas meter provided separately from the first gas meter based on the heating value of the gas of the first gas meter that is arranged within a predetermined range with respect to the second gas meter on a gas supply pipe configured to supply the gas. The gas meter system and a heating value estimation method can estimate a heating value of a gas with high accuracy.
