Abstract

Patente de Invenção: <B>''PROCESSO PARA A DETERMINAçãO DE PARâMETROS, COMO POR EXEMPLO NìVEL DE ENCHIMENTO, PRESSãO OU COMPOSIçãO GASOSA, EM RECIPIENTES FECHADOS''<D>. Para a determinação de parâmetros de recipientes fechados, em uma parede de recipiente (12) são excitadas vibrações mecânicas primárias. As vibrações secundárias, excitadas através das vibrações mecânicas primárias da parede de recipiente (12) no recipiente (10), que ocorrem dentro do espaço entre o fecho (12) e o líquido são captadas e analisadas, sendo que a partir da progressão da freq³ência constatada dessas vibrações determinam-se os parâmetros. Adicionalmente, também podem ser captadas e analisadas as vibrações primárias do fecho (12), sendo que a partir da freq³ência dessas vibrações primárias determina-se a pressão interna predominante no recipiente (10). As freq³ências das vibrações primárias e secundárias podem ser determinadas através de análise do espectro de freq³ência. As vibrações secundárias podem ser captadas separadamente das vibrações primárias devido ao fato de que só são captadas as vibrações ocorridas dentro de uma janela de medição temporal, dentro das quais as vibrações primárias já tenham sido atenuadas.
