<p><P>PROBLEM TO BE SOLVED: To provide a flow rate measuring apparatus for registering an unknown instrument if a device determination is erroneous at an instantaneous flow rate output from a flow rate measuring means, reconfirming the flow rate of the unknown instrument, and improving the precision in the device determination. <P>SOLUTION: The flow rate measuring apparatus comprises the flow rate measuring means 3, a flow rate information storing means 8 for storing flow rate values of the flow rate measuring means 3, a calculating means 6 for obtaining a difference between the flow rate values output from the flow rate measuring means 3, an instrument registering/storing means 7, a device determining means 9 for determining the device, and an unknown instrument registering means 10 for registering information on the device which can not be determined. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
