Abstract
A fluid conduit with a rectangular cross-section is divided into two parallel conduits. A vortex generating rod is disposed perpendicularly to the flow direction in one of the conduits. An ultrasonic wave is directed perpendicularly across the conduit to detect the Karman vortex streets. A sound absorbing material is located along the portion of the conduit wall where the ultrasonic waves exist for preventing the formation of standing waves.
