GAS SYSTEM AND ITS PROGRAM

摘要

PROBLEM TO BE SOLVED: To construct a system for easily detecting a gas consumption for each gas appliance without disassembling or modifying the gas appliance. SOLUTION: The gas system comprises a gas meter 2000 and a gas appliance side communication instrument 1000. The communication instrument 1000 transmits information on ignition or extinction obtained by a detection means 120 to the gas meter 2000. From the information and a gas flow recorded in a recording means 230, the gas meter 2000 calculates gas volume consumed by the gas appliance 3000. COPYRIGHT: (C)2007,JPO&INPIT
