Each of the ultrasonic transducers (transmitter and receiver) having either a sound generator or a sound receiver positioned between two vibrating elements. A connecting element clamps a sound generator with a sound receiver between the vibrating elements. Each of the ultrasonic transducers being supported by support elements featuring bent-off portions arranged in a meander-type manner in turn (bent back upon itself) in the housing. One of the support elements, for each transducer, is arranged at the sound opening of the housing and is slidably mounted on a vibrating element.
