Abstract

"métodos e aparelho de medida de fluxo de massa utilizando filtragem seletiva de modo". o fluxo de massa de um material em um conduto é estimado pela filtragem seletiva de modo de uma pluralidade de sinais de movimento (109) representando o movimento do conduto (100) para gerar uma pluralidade de sinais de movimento filtrados com seleção de modo (315) de modo que os sinais de movimento filtrados com seleção de modo preferencialmente representem o movimento associado com um modo de vibração do contudo. uma pluralidade de estimativas de fase (325) são geradas a partir da pluralidade de sinais de movimento filtrados com seleção de modo. uma estimativa de fluxo de massa (335) é gerada a partir da pluralidade de estimativas de fase. a pluralidade de estimativas de fase podem ser estimadas utilizando-se uma referência de fase (620) derivada a partir de um da pluralidade de sinais de movimento filtrados com seleção de modo. em algumas modalidades, uma freqüência (710) de um sinais de movimento filtrado com seleção de modo da pluralidade de sinais de movimento filtrados com seleção de modo é estimada. o primeiro e o segundo sinais de referência de quadratura (720) são gerados baseado na freqüência estimada. a pluralidade de estimativas de fase (740) são geradas a partir da pluralidade de sinais de movimento filtrados com seleção de modo do primeiro e do segundo sinais de referência. uma pluralidade de estimativas de referência de tempo b podem ser geradas a partir da pluralidade de estimativas de fase e a estimativa de fluxo de massa (630) pode ser gerada a partir da pluralidade de estimativas de diferença de tempo. a pluralidade de estimativas de diferença de tempo podem ser geradas a partir da pluralidade de estimativas de fase (530) dividindo-se a pluralidade de estimativas de fase utilizando uma freqüência do modo estimada a partir dos sinais de movimento filtrados com seleção de modo. a invenção pode ser incorporada como métodos ou aparelhos.
