Abstract
Un medidor de flujo Coriolis tiene un unico tubo de flujo recto, una barra de equilibrio paralela a dicho tubo de flujo, una barra de refuerzo que conectalos extremos de la barra de equilibrio con el tubo de flujo, y una cubierta circundante. Elequi librio dinámico mejorado del medidor de flujo es mantenido enrespuesta a cambios que ocurren en la densidad del material que pasa por el medidor reduciendo la funcion de resorte de la barra de equilibrio y/o tubo deflujo. Esto concentra lafuncion de resorte del medidor de flujo enla estructura de la barra de refuerzo. Un nodo de vibracion presente en la estructura debarra de refuerzo separa la funcion de resorte de la barra de equilibrio respecto de la funcion efectiva de resorte deltubo de fl ujo. El nodo de vibracion semueve dentro de la barra de refuerzo en respuesta a materiales de densidades diferentes que en momentos diferentes pasan por el tubo de flujo. Este movimientonodal hace que la funcion efectiva de resorte de labarra de equ ilibrio sea cambiada a la funcion efectiva de resorte del tubo de flujo, para mantener elmejorado equilibrio de vibracion dinámico del medidor de flujo sin implicar la masa de la cubierta. Se incluye además un método para equilibrar almedidor defluj o de manera dinámica.
