Abstract: A flow rate measurement device includes a flow rate measurer to measure a fluid flow rate at regular time intervals, a period setting unit, an arithmetic unit to calculate first average flow rates and amounts of change each between the average flow rates in sequence, and second average flow rates and amounts of change each between the average flow rates in sequence, and a fuel cell determinator to determine whether a fuel cell is in operation. The fuel cell determinator determines that a fuel cell is in operation when an increment of the second average flow rate repeats for first predetermined successive times, an increment of the first average flow rate repeats for second predetermined times or more in each of the second periods, and an increment of the first average flow rate not greater than or equal to a third predetermined flow rate in each of the second periods.

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.
