A device for measuring the velocity of a fluid flowing along a duct comprising a generally cylindrical member positioned in the duct for bodily oscillatory movement at right angles to the fluid flow in response to streams of periodic eddies generated by fluid flow therepast, and transducer means for providing a signal in response to such oscillatory movement. The member is situated and arranged so that the bodily motion thereof gives rise to a coherent two-dimensional eddy pattern in the flowing fluid. The member may be positioned in the duct by one or more flexures, by a plurality of springs, or by a magnetic levitation. |
