Abstract
A system for determining fluid velocity of a fluid flow to which the system is exposed, the system comprising: an acoustic structure including a radiating element and an acoustic volume acoustically coupled to the radiating element, a microphone located inside the acoustic volume, and a wire coupled to the radiating element such that, when the wire is subject to the fluid flow, vibrations of the wire are transmitted to the radiating element, and resulting vibrations of the radiating element radiate corresponding vibrations into the acoustic volume, wherein the microphone is sensitive to said vibrations radiated into the acoustic volume, and the output of the microphone in response to said vibrations is related to the fluid velocity of the fluid flow to which the wire is subject.
