Abstract

Ultrasonic measurement device for the displacement of objects in a fluid, characterized in that it includes: on the one hand, two acoustic probes placed side by side, each consisting of a piezoelectric sensor, a waveguide associated with said sensor and an impedance sensor. acoustic very different from that of said fluid, and a measurement line located in said fluid and delimited, on the one hand, by the end of said waveguide opposite to said sensor, on the other hand, by a surface and between the two, at least a focal mirror that focuses the acoustic waves emerging from said guide, of waves substantially on said surface which is, for one of said probes, the object to be examined, and, for the other, a reflector whose position is, precisely marked, which determines the length of said measurement line, and, on the other hand, a circuit for emitting electrical signals that excite said piezoelectric singers and a circ Uito of reception of the electrical signals coming from said piezoelectric sensors and due to the return acoustic waves, a switching system ensuring the passage from emission conditions to reception conditions.
