Abstract:
1. A gas meter comprising: a flow rate measurement section that measures a flow rate of gas flowing through a gas flow path; a flow rate computing section that calculates flow rate data based on flow rate measurement values measured by the flow rate measurement section; a function setting section that sets operation conditions for conditioning occurrences of anomalies to trigger security functions regarding a use of gas; a monitoring section that monitors, during the use of gas, an occurrence of any anomaly which is conditioned by one of operation conditions including said operation conditions set by the function setting section; a control section that initiates the security functions when an occurrence of an anomaly is detected by the monitoring section; and a communication section instructed by the control section to communicate with a monitoring center for managing a supply of gas, wherein said function setting section receives security function information indicative of a new operation condition which is transmitted from the monitoring center via the communication section and sets the new operation condition to condition an occurrence of an anomaly, and the security functions initiated by the control section comprises shutting off the supply of gas.
