PROBLEM TO BE SOLVED: To increase measurement accuracy by improving the flow of fluid and ultrasonic transmission. SOLUTION: Divider plates 3 divide a flow-passage into a plurality of divided passages 4. At least a pair of ultrasonic transceivers 7, 8 are arranged in order to measure the flow velocity of the fluid which flows in the divided passage 4. The ultrasonic transceivers 7, 8 are provided with piezoelectric vibrators 15, 16 in which slits 19, 20 are longitudinally formed. The formation direction of the slits 19, 20 and the setting direction of the divider plates 3 are identically set. Therefore, the longitudinal vibration generated in the piezoelectric vibrators 15, 16 propagates in each divided passage surely. COPYRIGHT: (C)2004,JPO
