Abstract

"MéTODOS PARA DETERMINAR UMA PROPRIEDADE DE ESCOAMENTO DE UM FLUIDO QUE PASSA ATRAVéS DE UM CONDUTO E PARA PROPORCIONAR CAPACITâNCIAS CORRIGIDAS USANDO UM SENSOR DE CAPACITâNCIA ANULAR PARA DETERMINAR UMA PROPRIEDADE DIELéTRICA DE UM FLUIDO DE TESTE EM UM CONDUTO, E, MEDIDOR DE CAPACITâNCIA". Método para determinar uma propriedade de escoamento de um fluido passando através de um conduto (1) munido de um medidor de capacitância que compreende u m sensor de capacitância anular a montante e a jusante (2a,2b), em que cada sensor de capacitância anular compreende pelo menos três eletrodos sensores (11a-13a, 11b-13b), cujos eletrodos sensores são distribuídos em torno da circunferência do conduto, o método compreendendo selecionar, para cada sensor de capacitância anular, um conjunto de capacitores de medição, em que um capacitor de medição é formado por dois eletrodos de medição, e em que um eletrodo de medição consiste quer de um único eletrodo sensor quer de pelo menos dois eletrodos sensores interligados; medir em vários momentos durante um intervalo de tempo uma capacitância de cada capacitor de medição de cada sensor de capacitância anular (2a, 2b), determinar correlações cruzadas entre capacitâncias medidas durante o intervalo de tempo no sensor de capacitância anular a montante (2a) e capacitâncias medidas durante o intervalo de tempo no sensor de capacitância anular a jusante (2b); e determinar a propriedade de fluência a partir das correlações cruzadas.
