Abstract

"TRANSDUTOR DE FLUXO MAGNéTICO E MEDIDOR DE FLUXO INCORPORANDO O MESMO". A presente invenção refere-se a um transdutor magnético (109) para medir o fluxo de um fluido (108) que tem eletrodos (102) e um campo magnético alternativo (107), um eletrodo (102) tendo energia de ruído mais baixa em freqüências abaixo de 5Hz do que um eletrodo compreendendo carbono ou liga de metal resistente à corrosão. A característica de ruído do eletrodo (102) em freqüências de campo magnético em torno de 1 Hz é mais baixa do que aquela de um eletrodo compreendendo carbono ou liga de metal resistente à corrosão.
