Abstract
A problem of the present invention is to provide a flow rate measurement device which is capable of simplifying calculation, reducing the amount of memory necessary for calculation, absorbing variations resulting from manual operation or ignition state when appliances are used alone or in combination, and improving appliance identification precision with a configuration which extracts characteristics of appliances. The flow rate measurement device monitors and determines the change in a flow rate measured by a flow rate measurement unit, monitors and determines the code obtained by differential conversion unit, extracts appliance characteristic flow rates representing the characteristics of the gas appliances, and compares them with the appliance-specific characteristics, thereby identifying the gas appliances.
