Abstract
Method and apparatus for measuring airflow in a duct utilizing the technique of vortex shedding include inducing the shedding of vortices at a frequency within the range of sound, sensing the sounds generated by the shedding of vortices to determine the frequency of vortex shedding, and converting the frequency of vortex shedding into information indicative of airflow measurements.
