Abstract

"MéTODO PARA CORRIGIR ERROS EM MEDIçõES DE TEMPO DE TRáNSITO PARA SINAIS ULTRASSÈNICOS E MEDIDOR ULTRASSÈNICO DE AUTO-SINTONIZAçãO". Um método e medidor ultrassónico correlacionado identificam e corrigem erros de tempo de trânsito, tais como erros de comutação de pico. O método inclui calcular valores de um conjunto de diagnósticos a partir de medições do fluxo de fluido, incluindo medições de tempo de trânsito. Com base nos valores para os diagnósticos, e se e como eles caem fora de suas respectivas faixas, o medidor pode identificar uma variedade de problemas com o medidor ou fluxo de fluido, tal como se existiu uma comutação de pico intermitente, uma comutação de pico permanente, ou a presença de ruído, pulsação de velocidade no fluxo de fluido, estratificação de temperatura, ou outro problema. Na eventualidade de existir um problema com o medidor, o medidor se auto-sintoniza a fim de minimizar as chances de o problema ocorrer novamente.
