Abstract (en)
[origin: WO2016181063A1] The invention relates to a method for detecting fluids by ultrasounds, using cells (10) that emit and receive ultrasound waves through a front face (8) which has an outer surface (12) in contact with the fluid to be detected in the outside environment (44), said method emitting ultrasound waves (40), then measuring the amplitude of the back waves received (42), coming from the reflection on the outer surface of the front face (12), and comparing same with that of the waves emitted.
