Abstract

"DISPOSITIVO MEDIDOR DE FLUXO BAIXO". A invenção provê um dispositivo medidor de fluxo baixo (10) para medir o fluxo de uma quantidade de líquido excedendo 0,05 ml, compreendendo uma primeira câmara (12) tendo uma entrada (14), e uma saída (16) em comunicação fluida com uma segunda câmara (17), a primeira câmara (12) contendo um elemento (22) criando um fluxo laminar (24) e a saída (16) da primeira câmara sendo provida com um gerador de gotas (19) conduzindo à segunda câmara (17) e dimensionado para liberar uma série de gotículas (18), cada uma das gotículas formando-se e rompendo-se sob seu próprio peso de líquido no orifício gerador de gotas, um conduto de transbordamento (21) estendendo-se entre uma área superior da primeira câmara (12) e uma área inferior da segunda câmara (17) para equalizar pressão de gás entre as duas câmaras (12, 17), meios eletrónicos (28) posicionados na segunda câmara (17) abaixo do gerador de gotas (19) para contar a passagem de cada gotícula (18) saindo dele, e uma unidade de processamento de informações (32) conectada ao meio eletrónico (28) para receber e registrar informações selecionadas do grupo consistindo de fluxo total (36), instante de partida (38), fluxo por unidade de tempo (34), condutividade elétrica de líquido (42 ) , tempo decorrido (40 ) e combinações destes.
