Abstract
The presence of interfaces located between at least two phases having close but different acoustic impedance values and two phases having relatively remote acoustic impedance values is detected, at least one of these phases being likely to contain solid particles. A device for detecting the presence of the interfaces includes a container linked to at least one intake pipe for a multiphase fluid, a first unit for generating an ultrasonic wave in a direction not parallel to an interface, this unit also being designed to receive a signal generated by a reflection of the wave on the interface, and a processing unit which enables various measurements to be taken and processed so as to calculate the quantity of at least one of the phases present in a multiphase fluid.
