Abstract

Una barra de compensacion para un caudalímetro de Coriolis de tubo recto. La barra de compensacion es preferentemente fabricada por un procedimiento queproporciona una cantidad aumentada de elementos de caudalímetro integrales con la barra decompens acion. Estos elementos integrales comprenden: barras deanclaje en cada extremo de la barra de compensacion, elementos de nervaduras a cada lado de la barra de compensacion para elevar la frecuencia de vibracion,lateral una superficie parafacilitar e l montaje de un excitador a la barra de compensacion y a un tubo de flujo circundado por la barra de compensacion,superficies para facilitar el montaje de sensores a la barra de compensacion y un tubo de flujo, huecos que bajan lafrecuencia resonant e de la barra decompensacion y en el modo de excitacion como también en el segundo modo de flexion. Una masa integral hace que la amplitud de la vibracion de la barra decompensacion sea menor que la del tubo de flujo. Dichoelemento que baja la frecu encia resonante de la barra de compensacion en el segundo modo de flexion hacetambién que el factor de calibracion del caudalímetro sea independiente de la densidad. La barra de compensacion es producida idealmente pormedio de unprocedimiento de mol deo en el que la totalidad de la barra de compensacion es formada, pero puede ser fabricada por cualquier procedimeiento, incluyendomecanizado, que produzca un caudalímetro que tenga algunos o todos los elementosarriba mencionados integrales al mism o.
