| Zusammenfassung: | The invention discloses a correlation acoustic water body flow velocity measuring device, and belongs to the field of hydraulic engineering measurement. The device comprises a composite metal bracket,a sound wave transmitting sensor, a sound wave receiving sensor, transducers and a computer, the composite metal support comprises a copper door-shaped frame and an aluminum door-shaped frame, the copper door-shaped frame is formed by pressing a brass sheet, and the thickness of the brass sheet is 3 mm, the aluminum door-shaped frame is formed by pressing any section aluminum alloy, and the thickness of the aluminum alloy is 4.5 mm. The copper door-shaped frame and the aluminum door-shaped frame are completely the same in overall dimension; and all the transducers are connected to the computer through a driving device. The novel device for measuring the flow velocity by using the acoustic correlation method can be used for measuring the flow velocity in an unimpeded and non-contact manner.
