摘要： A method for determining and/or monitoring a process variable of a medium, wherein a mechanically oscillatable unit is supplied with an exciter signal wherein a received signal coming from the mechanically oscillatable unit is received, and wherein the exciter signal is produced in such a manner, that a phase difference between the exciter signal and the received signal equals a predeterminable phase value. A criterion for judging the determining of the phase difference between the exciter signal and the received signal, or a signal dependent on the exciter signal or on the received signal, is established; in the case, in which the criterion for judging the determining of the phase difference is fulfilled, tuning of the phase difference is closed-loop controlled; and, in the alternative case, tuning of the phase difference is open-loop controlled. An apparatus associated with the method is also disclosed.
