Abstract

Metoda de masurare a nivelului conform inventiei utilizeaza timpul de parcurgere a unui fascicul ultrasonic de frecventa joasa care se propaga prin aer de la un emitator la un receptor fiind reflectat de suprafata baii metalice. Instalatia de reglare a nivelului cuprinde un generator de frecventa al carui semnal este convertit în oscilatii ultrasonice într-un emitator magnetostricitiv iar semnalul receptionat de un traductor electrodinamic comanda un circuit poarta ce actioneaza un generator de semnal declansat de generatorul de frecventa odata cu emiterea fasciculului de ultrasunete iar valoarea prescrisa si cea masurata si reglarea automata a nivelului pentru oricare topitura metalica sau nemetalica.
