Abstract

Device for detecting the variation of temperature of a fluid with the help of ultrasound, in which the variations in transit time of a train of ultrasonic waves propagating in a measurement line are detected, characterized in that it includes, on the one hand, a acoustic probe comprising a piezoelectric sensor, a waveguide associated with said sensor and of acoustic impedance very different from that of said fluid, a cylindrical tube that surrounds the end of said waveguide opposite to said sensor and that prolongs said guide, a converging mirror centered on the axis of said tube, a reflector that reflects the ultrasonic waves emerging from said waveguide and focused by said mirror on said reflector, a conduit that surrounds the acoustic wave beam from said mirror to said reflector, and means for fixing said tube, said mirror, said conduit and said reflector, which form with the end of said guide waves opposite said sensor a measurement line that is immersed in said fluid, and, on the other hand, a circuit for emitting electrical signals that excite said piezoelectric sensor and a circuit for receiving electrical signals from said sensor and due to the return acoustic waves, ensuring a switching system the transition from emission conditions to reception conditions.
