Como funciona
O medidor de fluxo/calor ultrassônico de canal duplo mede a taxa de fluxo real em cada ponto da tubulação através de dois grupos de sensores, simula a distribuição da taxa de fluxo no pipeline durante a operação real e resolve a precisão da conversão de velocidade linear V em velocidade da superfície Ѷ Para melhorar a precisão geral da medição do instrumento.
O medidor de fluxo/calor ultrassônico de canal duplo transmite e recebe ondas ultrassônicas entre si através dos sensores superior e a jusante. Quando o feixe ultrassônico se propaga no líquido, o fluxo do líquido fará uma pequena alteração no tempo de propagação, e a mudança no tempo de propagação é proporcional à taxa de fluxo do líquido, como mostrado na figura.
