An ultrasonic transducer for an ultrasonic flowmeter includes: a transducer housing with an ultrasound window; a transducer element in the transducer housing that transmits ultrasonic signals onto a signal path and receives ultrasonic signals from the signal path; a control and evaluation unit that controls the transducer element and evaluates the ultrasonic signals; and a buffer element that forms at least one at least partially reflective boundary layer in the signal path. In an operating state, the transducer element transmits an ultrasonic signal that is at least partially reflected at the boundary layer of the buffer element, and the reflected signal component is received by the transducer element. The control and evaluation unit monitors the reception of the reflected signal component and, in the absence of reception of a reflected signal component, detects an error state of the ultrasonic transducer.
