Abstract: The acoustic waveguide has a flexible metal rod with a cylindrical waveguide rigidly attached to each end of the same through a conical acoustic concentrator. One cylindrical waveguide is capable of being attached to an electroacoustic transducer and the other cylindrical waveguide is capable of being attached to an acoustic oscillation receiver. The structure provides for the enhanced functional capabilities of the acoustic waveguide by utilizing it in devices operating under conditions of high temperature, radiation, strong electromagnetic interferences and other negative factors.

Abstract: The fluid-level sensor has an acoustic waveguide comprising a flexible metal rod, an electroacoustic transducer coupled to one end of the acoustic waveguide and an acoustic resonator coupled to the other end of the acoustic waveguide. The flexible metal rod has two ends, one cylindrical waveguide coupled via a conical acoustic concentrator to one end of the flexible metal rod, the other cylindrical waveguide coupled via a conical concentrator to the other end of the flexible metal rod. One cylindrical waveguide is coupled to the electroacoustic transducer and the other cylindrical waveguide is coupled to the acoustic resonator. The structure provides for the enhanced functional capabilities of the sensor by using it under the conditions of high temperature, radiation, strong electromagnetic interference, intense vibrations, impacts, and other negative factors. The sensor can be installed, maintained, and repaired without hazard to servicing personnel.
