Ultrasound detection method of the appearance of a gas phase in a phase liquid contained in a pregnant. |
| abstract |
Method for ultrasonic detection of the appearance of a gaseous phase in a liquid phase contained in an enclosure, characterized in that it consists of: - passing trains of the enclosure and the liquid through waves of frequency greater than 20 KHz, of duration of the order of 10-3s and sufficiently spaced over time, to avoid any overlap of the reception signals collected at their exit from the enclosure; detecting, with at least one ultrasonic receiver, the overall output signal transmitted through the enclosure-liquid phase system; in separating, in this received global signal, the useful part corresponding to the crossing of the liquid phase; to detect for this useful part of the signal, the possible damping of the amplitude characteristic of the presence of a gaseous phase in the liquid phase. |
