Abstract
Flow rate measurement device includes flow rate measurement unit that measures a flow rate of gas at a prescribed time interval, and arithmetic unit that calculates a characteristic flow rate from the flow rates measured within a predetermined period, and calculates a ratio of each flow rate measured at multiple times within the predetermined period with respect to the characteristic flow rate. In addition, flow rate measurement device includes appliance characteristic extraction unit that extracts an appliance characteristic quantity which indicates a characteristic of a flow rate change in currently using gas appliances within the predetermined period, the appliance characteristic quantity being the ratio or information obtained from the ratio, and appliance inherent characteristic information holding unit that holds an appliance inherent characteristic quantity indicating a characteristic flow rate state of a specific gas appliance. Furthermore, flow rate measurement device includes appliance discrimination unit that discriminates the currently using gas appliance by comparing the appliance characteristic quantity with the appliance inherent characteristic quantity.
