Abstract

Un aparato para medir las características de un material que fluye a través del mismo y un método para colocar un excitador en al menos un conducto delaparato. El aparato, por ejemplo un caudalímetro de masa de Coriolis o densímetro de tubovibrante, tiene un excitador o escitadores para induciroscilacion de por lo menos un conducto. Los excitadores están vinculados a ubicaciones a lo largo del conducto vibrante seleccionada para incluir ciertosmodos de interés. Un excitador estáu bicado cerca de un área de máxima amplitud de un modo de vibracion deseado y cerca de un área de mínima amplitud de unmodo de vibracion indeseado. Se utilizan diversas técnicas de análisis modal y modelamiento experimentales conocidas paradetermina r las ubicacionesapropiadas para uno o más excitadores. Multiples excitadores ubicados de acuerdo al presente invento son utilizdos para incluir, es decir, excitar osuprimir, modos multiples. Además, multiples circuitos deexcitacion separados producen multiples senales e excitacion eléctricamente separadas paraproporcionar mayor potencia total al conducto vibrante.
