Title:
GAS METER SYSTEM AND METHOD FOR DERIVING HEATING VALUE
Document Type and Number:
Japanese Patent JP2016206037
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a gas meter system that can accurately derive the heating value of a gas.SOLUTION: A gas meter system 100 includes a gas meter 110, a gas generating factory 114, and a center device 116. The gas meter 110 has a sound velocity deriving unit deriving the sound velocity of a gas supplied in a part with demand. The gas generating factory 114 has a gas generating unit generating gas and a gas characteristic specifying unit specifying gas characteristics showing the relation between the sound velocity and the heating value of the gas generated by the gas generating unit, based on the result of analyzing the components of the gas. The sensor device 116 has a gas heating value deriving unit deriving the heating value of a gas passing through the gas meter based on the sound velocity of the gas derived by the sound velocity deriving unit of the gas meter and the gas characteristics specified by the gas characteristic specifying unit of the gas generating factory.SELECTED DRAWING: Figure 1
