Abstract
A gas appliance monitoring apparatus includes a flow rate measurement unit for measuring the gas flow rate, a gas shut-off valve for shutting off a gas flow path at the abnormal time, an information storage unit for storing measurement results of the flow rate measurement unit, a wireless module for transmitting and receiving information, and a communication switch unit for switching a communication frequency band. The wireless module is integrated with a control circuit board forming the flow rate measurement unit and is housed in a gas meter. The wireless module has at least a communication frequency band with a base station and a communication frequency band with a plurality of gas appliances, and transmits an operation start signal detected by a specific gas appliance as appliance information using an appliance wireless module. The continuous use time of the specific appliance is detected or is changed based on the information.
