摘要： A gas meter (10) includes a normal measurement mode in which the flow rate is measured in a predetermined sampling period and a detailed measurement mode in which the flow rate is measured in a sampling period shorter than the predetermined sampling period in the normal measurement mode. A center device (40) gives an instruction to the gas meter (10) to measure the flow rate in the detailed measurement mode. The center device (40) further collects flow rate data measured in the detailed measurement mode from the gas meter (10), and generates, based on the collected flow rate data, failure diagnosis information for diagnosing a failure in a gas appliance. With this configuration, the failure part in the gas appliance can be remotely identified, which accelerates the repair work.
