Abstract

Patente de Invenção para "CONTROLADOR DE FLUXO DE MASSA DE CORIOLIS". Um sensor de fluxo de massa de Coriolis inclui um tubo de fluxo, uma fonte de luz posicionada adjacente a um primeiro lado do tubo de fluxo, e um detector de luz posicionado adjacente a um segundo lado do tubo de fluxo. Um dispositivo de acionamento está operativamente situado em relação ao tubo de fluxo para vibração do tubo de fluxo, tal que o tubo de fluxo se move através de uma trajetória definida entre a fonte de luz e o detector de luz. Em outros aspectos da invenção, o sensor de fluxo de massa de Coriolis inclui um tubo de fluxo e uma estrutura tendo o tubo de fluxo montado na mesma. Um dispositivo de acionamento está operativamente situado em relação à estrutura para vibração da estrutura, e pelo menos um sensor captador está situado em relação ao tubo de fluxo de modo a medir o torcimento no tubo de fluxo devido à força de Coriolis. Outros aspectos da invenção se referem a um sensor de fluxo de massa de Coriolis de tubo reto. Um tubo de fluxo flexível define uma trajetória de fluxo geralmente linear. Um dispositivo de acionamento está posicionado para atuar o tubo de fluxo, e primeiro e segundo sensores captadores estão posicionados nas primeira e segunda extremidades do tubo de fluxo, respectivamente. Os primeiro e segundo sensores captadores produzem um sinal em resposta ao movimento do fluxo de tubo, no qual uma força de Coriolis estabelecida por um fluxo de material através do tubo de fluxo, causa uma alteração de fase entre a saída de sinais pelos primeiro e segundo sensores captadores.
