Abstract

Procedimento di rilevazione tramite ultrasuoni dell'apparizione di una fase gassosa in una fase liquida contenuta in un recipiente, caratterizzato dal fatto che esso consiste:- nel far passare, attraverso il recipiente ed il liquido, treni di onde di frequenza superiore a 20 kHz, di durata dell'ordine di 10 alla -3 se sufficientemente distanziati nel tempo, per evitare qualunque sovrapposizione dei segnali di ricezione raccolti alla loro uscita dal recipiente;- nel rivelare, con almeno un ricevitore di ultrasuoni, il segnale globale di uscita trasmesso attraverso il sistema recipiente-fase liquida;- nel separare, in questo segnale globale ricevuto, la parte utile corrispondente all'attraversamento della fase liquida;- nel rilevare, per questa parte utile del segnale, l'eventuale smorzamento dell'ampiezza caratteristica della presenza di una fase gassosa nella fase liquida.Figura 1.
