<P>PROBLEM TO BE SOLVED: To provide a flowmeter that can measure, especially a volume flow rate and/or a mass flow rate of a fluid, and is usable for a wide measurement range and also usable even at a high flow velocity. <P>SOLUTION: The flowmeter includes at least one ultrasonic sensor (114) for detecting at least one first flow characteristic of the fluid, and at least one effective pressure sensor (116) for detecting at least one second flow characteristic of the fluid. <P>COPYRIGHT: (C)2012,JPO&INPIT |
