Abstract
Object of the present invention is to measure the quantity of a gas flowing through a gas meter and accurately calculate, on a per-appliance basis, the quantity of used gas in each time during which a gas appliance connected to a downstream point is used, without involvement of a waveform pattern. A flow rate measuring apparatus () has a flow rate measurement unit that measures a flow rate at given time intervals; an appliance determination unit that calculates a flow difference between flow rates acquired at two arbitrary times by measuring the use of an appliance connected to a downstream point with reference to the flow rate measurement unit, thereby determining an operating appliance; and an appliance flow rate calculation unit that calculates the appliance-specific usage flow rate by switching a calculation method according to the number, types, combinations, and priority levels of currently-operating gas appliances that are results of determination made by the appliance determination unit.
