Abstract

Sistem de contorizare a fluidelor, bazat pe metoda micşorării locale a secţiunii de curgere, care, în scopul măsurării parametrilor din conducta de distribuţie, este utilizat un set de senzori cuprinzând un senzor de presiune (4), un senzor de presiune diferenţială (5), un senzor de temperatură de compensare (6) şi un senzor de temperatură a fluidului (7), senzorii fiind alimentaţi cu tensiune de la un întrerupător electronic (8), numai pe durata măsurării, tensiunile ce apar la ieşirile senzorilor menţionaţi fiind multiplexate cu ajutorul unui multiplexor analogic (9) şi aplicate la intrarea unui convertor analogic-digital (10), semnalul digital de tensiune fiind prelucrat într-un microcalculator (11), care realizează calcularea şi contorizarea debitului de fluid, la anumite intervale de timp, între care sistemul este trecut într-o stare de consum mic de energie electrică, mărimile măsurate fiind afişate pe un afişaj (13) sau transmise la distanţă printr-o interfaţă digitală (14), întregul sistem fiind alimentat de la o baterie (15).
