The device is designed to excite the mechanically vibrating unit to mechanical vibrations using an excitation signal, to receive the mechanical vibrations of the vibrating unit and convert them into a first reception signal, to emit a transmission signal, and to receive a second reception signal. The electronic unit is designed to determine the at least one process variable of the medium based on the first and/or second reception signal.
