Abstract
A system for detecting velocity airflow in a duct includes a plurality of vortex shedders arranged within the duct for inducing the shedding of vortices at a corresponding plurality of selected locations at a frequencies related to the airflow in the duct and a sound-sensing location on each vortex shedder. A plurality of microphones, each microphone being coupled acoustically with each sound-sensing location senses sounds generated by said shedding of vortices in a corresponding passage and provides an information signal indicative of said vortex shedding sounds. A processing unit performs a Fast Fourier Transform on the information signals to determine frequency of maximum amplitude within the information signals.
