Abstract
A piezoelectric, acoustic vibration detecting element is positioned in a fluid flow to be measured so as to be moved according to the intensity of the fluid flow away from a source of acoustic vibration. As the distance between the acoustic vibration source and the element increases with increasing fluid flow intensity, reducing the acoustic pressure on the element, the magnitude of an electrical output signal produced by the element decreases providing a detectable measurement of the change in the fluid flow intensity.
