A small, compact, easily mountable ultrasonic transducer for measuring the filling level in a container is provided, which transducer transmits virtually no oscillation energy to the container, having a can-shaped transducer housing (1), an electronics housing (2) connected to the transducer housing (1), a transducer element (4), arranged in the transducer housing (1), for the transmission and reception of ultrasonic pulses, a union ring (3) for the sound-decoupling securing of the ultrasonic transducer on the container, in which ring the transducer housing (1) is supported coaxially with respect to the union ring (3) and is fixed therein against displacement in the axial direction, and two resilient elements (7, 8) which are arranged between the transducer housing (1) and the union ring (3) and by means of which the transducer housing (1) and the union ring (3) are held spaced apart from each other in the radial direction in such a way that there is no direct mechanical coupling between them in the radial direction.
