Abstract

método para determinar não invasivamente a composição de um fluido de multifases. é descrito um método para determinar a composição de fluidos que escoam através de tubos a partir de medições não invasivas de propriedade acústicas do fluido, que inclui excitar um primeiro transdutor localizado na superfície externa do tubo através do qual o fluido está escoando, para gerar um sinal de ultrassom com frequência variável, ao contrário de pulsos convencionais. o sinal com frequência variável é recebido por um segundo transdutor disposto na superfície externa do tubo oposto à localização do primeiro transdutor, a partir do qual o tempo de trânsito através do fluido é determinado e a velocidade do ultrassom no fluido é calculada. a composição de um fluido é calculada a partir da velocidade do som nele. a densidade do fluido pode também ser derivada de medições de atenuação do som. diversas abordagens de processamento de sinal são descritas para extrair a informação de tempo de trânsito dos dados com os efeitos da parede do tubo tendo sido subtraídos.
