Abstract

Un medidor de caudal Coriolis tiene tubos de flujo con un excitador en la porcion dinámicamente activa de los tubos de flujo y sensores acoplados almismo. Los tubos presentan ondulaciones que aumentan la flexibilidad de éstos, de modo que responden en mayor medida a fuerzas Coriolis. Esto mejora lasensibilidad del medidor de caudal. Ondulaciones en un tubo de flujo recto reducen esfuerzos inducidos térmicamente en el tubo de flujo cuando el largoaxil del mismo es restringido por una cubierta circundante o un tubo equilibrador o compensador en el que están asegurados los extremos del tubo deflujo. Las ondulaciones pueden ser dispuestas de manera selectiva sobre el tubo de flujo para controlar la respuesta que el tubo de flujo tiene a la vibraciondel modo de excitacion fundamental y también a las armonicas del mismo.
