  • Heating value derivation device and heating value derivation method
    Patent number: 10613056
    Abstract: A heating value derivation device includes a sound velocity derivation unit configured to derive a sound velocity of a gas flowing through a gas flow path, and a heating value derivation unit configured to refer to correspondence relationship information to derive a heating value per unit volume of the gas.
    Type: Grant
    Filed: March 11, 2016
    Date of Patent: April 7, 2020
    Assignee: TOKYO GAS CO., Ltd.

  • HEATING VALUE DERIVATION DEVICE AND HEATING VALUE DERIVATION METHOD
    Publication number: 20180100831
    Abstract: A heating value derivation device and a heating value derivation method. A gas meter as a heating value derivation device includes a sound velocity derivation unit configured to derive a sound velocity of a gas flowing through a gas flow path, a heating value derivation unit configured to refer to correspondence relationship information that enables a heating value per unit volume to be uniquely derived from the sound velocity of the gas, to thereby derive the heating value per unit volume of the gas, which is independent of a type of the gas, based on the sound velocity derived by the sound velocity derivation unit, and a flow rate derivation unit configured to derive a flow rate of the gas that has passed through the gas flow path. Thus, a passage heating value of the gas can be derived.
