Abstract

PARA LA OBTENCION DE UN TUBO (13) DE MEDICION DE FORMA HELICOIDAL BASADO EN SENSOR DE FLUJO DE MASAS SEGUN EL PRINCIPIO DE CORIOLIS, EL SENSOR PUEDE ESTAR MONTADO POR EJEMPLO POR MEDIO DE BRIDAS (11,12) EN EL PASO DE UNA TUBERIA DISPONIENDO DE UN DIAMETRO (DN) A TRAVES DEL CUAL FLUYE EL FLUIDO A SER MEDIDO Y DISPONE DE MODOS DE VIBRACION AMPLIAMENTE COMPENSADOS DE FORMA INDEPENDIENTE DE LA DENSIDAD DEL FLUIDO, MIENTRAS QUE SE MANTIENE SU PROPIA CAPACIDAD DE AUTOVACIADO EN AL MENOS UNA POSICION DE MONTAJE. LA PARTE (13'') DE VIBRACION DEL TUBO (13) DE MEDIDA ESTA PERFILADA COMO UNA HELICE CILINDRICA CIRCULAR CON UN PASO CONSTANTE Y AL MENOS UN ARROLLAMIENTO. EL EXTREMO CORRESPONDIENTE DE UN TUBO (15) SOPORTE ESTA ASEGURADO AL TUBO (13) DE MEDICION DE FORMA PROXIMA CON RESPECTO A LA BRIDA (11,12) O A LA MISMA BRIDA CORRESPONDIENTE. SOLAMENTE EL EXTREMO CORRESPONDIENTE DE UN ELEMENTO (14) DE SOPORTE INTERIOR SE ASEGURA AL TUBO (13) DE MEDICION DE FORMA PROXIMA A LA BRIDA (11,12). LOS ELEMENTOS(16) DE UNION DISPONEN DE JUNTA DE LA PARTE (13'') DE VIBRACION AL ELEMENTO (14) DE SOPORTE, ESTAN DISTRIBUIDOS A LO LARGO DE LA PARTE (13'') DE VIBRACION Y PERMITEN SOLAMENTE AQUELLOS MODOS DE VIBRACION DE LA PARTE (13'') VIBRATORIA EN DONDE SU LINEA CENTRAL PERMANECE SOBRE LA SUPERFICIE QUE ENVUELVE LA POSICION CILINDRICA RESTANTE. SE DISPONEN DE MEDIOS PARA EXCITAR LA PARTE (13'') DE VIBRACION DENTRO DE VIBRACIONES RESONANTES DE FORMA PERPENDICULAR CON RESPECTO A SU LINEA CENTRAL.
