Title: Ultrasonic vortex flowmeter
Inventor: KASHIMOTO HIROO
IPC: G01F1/32
Filed: 1998-12-18
Abstract: PROBLEM TO BE SOLVED: To enhance S/N ratio in an ultrasonic vortex flowmeter by reducing sneak noises which propagate through a bluff body and a meter body. SOLUTION: A measurement passage 17 is formed inside a bluff body 16 provided across the flow passage 14 of the mater body 15, the measurement passage 17 being communicated with the flow passage 14 by holes 18, 19. Ultrasonic wave transceivers 20, 21 opposite each other across the measurement passage 14 are attached to both ends of the bluff body 16. Circulation of gas in the flow passage 14 generates a Karman vortex causing fluctuation of flow velocity within the measurement passage 17. This flow is detected by means of the ultrasonic transceivers 20, 21 so as to measure the flow rate of the gas. The cylinder parts of the sensor holders 28 of the ultrasonic transceivers 20, 21 are welded together by means of coupling parts 35 into a split structure.  Since ultrasonic waves propagating through the cylinder parts of the sensor holders 28 are reflected and attenuated by the boundary faces of the coupling parts 35, sneak noises which propagate through the bluff body 16 and the meter body 15 are reduced whereby S/N ratio is enhanced.
