ABSTRACT:
A gas flow monitor has a T-shaped member adapted to conduct the gas flow of interest between its arms while a pressure transducer is disposed in its leg. A vortex or turbulence within the gas flow is generated within the T-shaped member to produce acoustic waves indicative of the magnitude and direction of the gas flow. The vortex is generated by providing a transversal rod in said T-shaped member, and by terminating one of the arms by an acoustic resonator.
