Zusammenfassung: | The present invention consists of a fluid flow meter that calculates the speed and direction of a fluid according to the drag force it exerts on a solid body. It consists of a spherical parallel mechanism formed by a fixed base (1) that allows spherical movement to a mobile platform (7) by means of a mast (2) and two kinematic chains (3). Solidarity to the platform (7) a tube (8) supports a spherical container (9) provided inside it with an inertial measurement unit (10), which records the spatial orientation of the platform (7) with respect to the fixed base ( 1) generated by the action of the fluid on the spherical container (9). This device can be used to measure water or air currents, as a support instrument in boat navigation and for measuring fluid currents in channels or pipes.

La presente invención consiste en un medidor de corrientes de fluidos que calcula la velocidad y dirección de un fluido según la fuerza de arrastre que éste ejerce sobre un cuerpo sólido. Consta de un mecanismo paralelo esférico formado por una base fija (1) que permite movimiento esférico a una plataforma móvil (7) mediante un mástil (2) y dos cadenas cinemáticas (3). Solidaria a la plataforma (7) un tubo (8) soporta un recipiente esférico (9) provisto en su interior de una unidad de medición inercial (10), que registra la orientación espacial de la plataforma (7) respecto de la base fija (1) generada por acción del fluido sobre el recipiente esférico (9). Este dispositivo puede utilizarse para medición de corrientes de agua o aire, como instrumento de apoyo en navegación de embarcaciones y para medición de corrientes de fluidos en canales o tuberías. |
