  The gas control device 1 is composed of a gas valve 2, a flow rate measuring means 9 for measuring a passing flow rate, a communication means 3 for transmitting / receiving various information, a gas supply availability determining means 4 and the like. The gas meter 10 is housed inside and installed in each home, and is disposed at the entrance of a gas pipe to be supplied to the home. A gas appliance (not shown) in the home is located downstream of the gas meter 10. It is connected. The communication means 3 communicates with other gas control devices 6, 7, etc. installed in a neighboring home, communicates with the centralized monitoring center 5, and communicates with the information display terminal 8.

  As shown in FIG. 2, the gas meter 10 incorporating the gas control device 1 is provided with a gas valve 2 for shutting off the gas flow path at the entrance of the gas pipe at the time of abnormality, and the gas flow path at the appropriate downstream side thereof. A flow rate measuring means 9 for measuring the passing flow rate, for example, an ultrasonic sensor is disposed therein. The flow rate signal detected by the flow rate measuring means 9 is sent to the control circuit 11 and converted into a flow rate value by the control circuit 11, and the amount of gas used is managed and the abnormal flow rate is monitored by the flow rate value data.

  Further, the control circuit 11 is integrally incorporated with a drive circuit for driving the gas valve 2, a gas supply availability determination means 4 for determining the availability of gas supply from various information, and a communication means 3 for transmitting and receiving various information.
