PROBLEM TO BE SOLVED: To obtain a desired combustion output for a combustion control in gas equipment, even though a plurality of kinds of fuel gases are conducted in a gas pipe network. SOLUTION: Gas equipment 2 is connected to a gas pipe network 1, in which a plurality of kinds of fuel gases are conducted. A gas meter 10 with a gas measuring part 11 for measuring a volumetric flow-rate of the fuel gas consumed by the gas equipment 2 is provided in a pipe 5 connected to the network 1. A measuring part 11 monitors simultaneously the fuel-gas component, and adjusts the combustion in a burning appliance 20 of the gas equipment in accordance with a variation in a gas-component detected by the measuring part 11 to maintain the combustion output to a desired value. As a preferable example, fuel-gas component data is sent from a gas meter 10 to a combustion-control part 21 which controls a fuel-gas amount and a combustion-air amount supplied to the burning appliance 20. The control part 21 controls the fuel-gas supply amount in accordance with the component data, so that the combustion output becomes a desired value.
