Abstract

"MéTODO E APARELHO PARA UM MEDIDOR DE FLUXO CORIOLIS POSSUINDO SEU FATOR DE CALIBRAGEM DO FLUXO INDEPENDENTE DA DENSIDADE DO MATERIAL" Trata-se de um medidor de fluxo Coriolis de tubo único com sensibilidade ao fluxo acentuada, no qual o fluxo de material induz deflexões Coriolis em um tubo de fluxo e deflexões tipo Coriolis em uma barra de equilíbrio vibracionalmente acoplada com o tubo de fluxo. Tanto as deflexões Coriolis como as deflexões tipo Coriolis possuem um deslocamento de fase determinado pelo fluxo de material e são utilizados de forma coadjuvante para derivar a informação sobre o fluxo do material. O medidor de fluxo alcança uma sensibilidade ao fluxo constante através de uma faixa de alterações na densidade do material por 1) variar a sensibilidade ao fluxo em uma primeira direção sob controle da relação entre a amplitude de vibração do modo de acionamento do tubo de fluxo e da barra de equilíbrio e 2) variar a sensibilidade ao fluxo em uma direção oposta sob controle de relação entre a amplitude da deflexão Coriolis do tubo de fluxo e da deflexão tipo Coriolis da barra de equilíbrio. A relação da amplitude de vibração do modo de acionamento varia com as alterações na freq³ência do modo de acionamento causadas pelas alterações na densidade do material. A relação de amplitude da deflexão Coriolis com a deflexão tipo Coriolis altera-se com as alterações na magnitude da separação da freq³ência do modo de acionamento e a freq³ência do segundo modo de curvatura para equilibrar a densidade da barra de equilíbrio que, por sua vez, é causada pelas alterações na densidade do material.
