Abstract
a presente invenção refere-se a um sensor de fluxo que compreende um restritor de fluxo disposto dentro de uma passagem de modo que um fluido que atravessa a passagem precise atravessar o restritor de fluxo. o sensor de fluxo também tem um sensor de pressão a montante acoplado à passagem em um ponto a montante do restritor de fluxo e configurado para medir e fornecer uma pressão a montante do fluido dentro da passagem, um sensor de pressão a jusante acoplado à passagem em um ponto a jusante do restritor de fluxo e configurado para medir e fornecer uma pressão a jusante do fluido dentro da passagem, e um sensor de temperatura acoplado à passagem e configurado para medir e fornecer uma temperatura do fluido dentro da passagem. o sensor de fluxo também inclui um processador de sensor de fluxo acoplado aos sensores de pressão a montante e a jusante e ao sensor de temperatura e configurado para aceitar medições do mesmo e calcular uma taxa de fluxo compensado com base pelo menos em parte nas pressões e temperatura medidas.
