Abstract

Un caudalímetro de Coriolis que tiene un unico tubo de flujo y una barra de compensacion que mejora la sensibilidad del caudalímetro al flujo de material.El diseno de la barra de compensacion disminuye la respuesta de su segundo modo de flexion paraque tenga una frecuencia que pueda ser inferior a la frecuenciade excitacion resonante del tubo de flujo. La disminucion de la frecuencia del segundo modo de flexion de la barra de compensacion permite que la respuesta deCoriolis del tubo de flujovi brante con flujo de material transmita fuerzas del tubo a través de una barra de anclaje a la barra de compensacion. Estas fuerzasde Coriolis inducen vibraciones con respuesta similares a Coriolis en la barra de compensacion debido a lafrecuencia di sminuida del segundo modo de flexion dela barra de compensacion. La respuesta de Coriolis del caudalímetro es mejorada ya que la respuesta similares a Coriolis de la barra de compensacion está fuerade fase con, y es aditiva paradeflexion de Coriolis del tubo de flujo.
