Abstract:
1. A flow rate measurement apparatus comprising: a flow rate measurement unit for measuring a flow rate of a fluid flowing into a flow path; a flow rate information storage unit for storing a flow rate value measured in the flow rate measurement unit; an appliance registration storage unit for storing the flow rate value for each appliance of a plurality of appliances; an appliance determination unit for making a comparison between a flow rate pattern of the flow rate value measured in the flow rate measurement unit and a flow rate pattern of an appliance determination value stored in the appliance registration storage unit and determining a use state of an appliance connected to a downstream side of the flow rate measurement unit solely from the flow rate value; and an unknown appliance registration unit for registering the use state as unknown data when there is a flow rate pattern according to which the appliance determination unit cannot determine the appliance based on information in the appliance registration storage unit; and a recheck unit for rechecking the unknown data based on the data in the flow rate information storage unit to determine if registration data exists in the unknown appliance registration unit.
