Abstract
A flow amount measuring and controlling apparatus which has a built-in gas meter can compute and control the flow amount used for each gas appliance by the estimation of the gas appliance generated in the flow variation from the change of the monetary flow amount passing through the gas meter, whereby, since the condition of the gas appliance can be correctly determined, the abnormal operation of the gas appliance can be detected so as to shut off the gas.
