A vibronic sensor for monitoring a flowable medium, comprising: an oscillator to which a medium surrounding the oscillator can be applied; at least one electromechanical transducer for exciting the oscillator to mechanical vibrations in accordance with driver signals and/or for outputting transducer signals that depend on vibrations of the oscillator; an operating and evaluating unit for providing the driver signals for driving the electromechanical transducer, for capturing the transducer signals, and for determining the presence, the density, and/or the viscosity of the medium in accordance with the transducer signals, wherein the operating and evaluating unit is designed to detect whether the medium in the pipe has a flow velocity above a limit value on the basis of time-varying modifications of the transducer signals.
