Abstract

Patente de Invenção para <B>"CONTROLADOR DE FLUXO DE MASSA DE CORIOLIS"<D> Um sensor de fluxo de massa de Coriolis inclui um tubo sensor de fluxo, um dispositivo de acionamento situado em relação ao tubo sensor de fluxo, de modo a fazer com que o tubo sensor de fluxo vibre, e sensores captadores situados em relação ao tubo sensor de fluxo, de modo a medir o torcimento no tubo sensor de fluxo devido a força de Coriolis. Um sensor captador capacitivo é revelado, que inclui pelo menos uma placa condutiva conectável a um primeiro potencial de voltagem e adaptada para estar situad adjacente ao tubo sensor de fluxo que está conectado a um segundo potencial de voltagem. A placa condutiva é posicionada em relação ao tubo sensor de fluxo de modo a definir uma folga entre os mesmos. A capacitância entre a placa condutiva e o tubo sensor de fluxo varia devido ao movimento relativo da placa condutiva, e ao tubo sensor de fluxo quando o tubo sensor de fluxo é vibrado. Acionadores eletromagnéticos, acústicos e/ou piezoelétricos podem ser usados para vibrar o tubo sensor de fluxo. O controlador de fluxo de massa de Coriolis pode incluir adicionalmente um dispositivo de controle de fluxo integrado adaptado para receber fluido a partir do tubo sensor de fluxo, e proporcionar controle de fluxo.
