The present invention relates to a method for determining and/or monitoring at least a first process variable and a second process variable of a medium (M) in a container (3), wherein: a sensor unit (2) is excited by means of an excitation signal (A) in order to cause mechanical oscillations of the sensor unit; the sensor unit (2) receives the mechanical oscillations and converts them into a first receive signal (EA); the sensor unit transmits a transmit signal (S) and receives a second receive signal (ES); and a first process variable is ascertained on the basis of the first receive signal (EA) and a second process variable is ascertained on the basis of the second receive signal (ES). According to the invention, the transmit signal (S) is selected such that, between a first component of the sensor unit (2) and a second component of the sensor unit (2) or a wall of the container (3), a standing wave is produced at least in part of the medium (M).
