Device and method for measuring fluid streams by parallel spherical mechanism actuated by drag forces

摘要

The present invention is a meter fluid streams calculates the speed and direction of a fluid according to the drag force it exerts on a solid body. Comprises a spherical parallel mechanism formed by a fixed base (1) allowing spherical movement to a mobile platform (7) by a mast (2) and two kinematic chains (3). Secured to the platform (7) a tube (8) carries a spherical container (9) provided inside an inertial measurement unit (10) which records the spatial orientation of the platform (7) with respect to the fixed base ( 1) generated by action of the fluid on the spherical container (9). This device can be used for measuring water or air streams, as a support for navigation of vessels and measurement of fluid streams in channels or pipes.
