Abstract
The invention relates to an instrument for measuring air speed by means of parabolic movement and to a measuring method, wherein the measuring instrument is formed by a cubic structure (1) that holds a screwable, flexible container (2) which releases—where air speed needs to be measured—a drop of liquid, the drop falling on one of the concentric circles located on an interchangeable plate (3) that is positioned on a flat base (4) of the device and perpendicular to the axial end of the outlet for the drop of liquid. Depending—on the height—the movement with which the drop falls, the air speed can be determined by means of the horizontal range of the parabolic movement followed by the drop of liquid, and evaluated using the distance be ween the point of impact of the drop on the surface with respect to the center. The direction of the air speed can also be determined from angle formed by the projection of the vertical plane above which projection the air moves in relation to the x-axis of the x-y plane located above the interchangeable plate (3).
