Abstract

<B>APARELHO E MéTODO DE PRECISãO DE MEDIçãO DE VOLUME DE LìQUIDOS<D> A presente invenção refere-se a um sistema e a um método para a compensação de um desvio previsto do medidor, em um medidor de deslocamento positivo, que compreende um pulsador conectado ao medidor, para a geração de um fluxo de pulso indicativo de um volume atual enviado através do medidor, e um processador de pulso em comunicação eletrónica com o gerador de pulso. O processador de pulso adiciona ou subtrai pulsos indicativos do inverso do desvio previsto do medidor ao ou do fluxo de pulso, para criar um fluxo de pulso corrigido. A quantidade de inversão aplicada é determinada pelo valor do volume cumulativo atual passado pelo medidor.
