The method entails receiving a vibrational response from the flow meter (5), wherein the vibrational response comprises a response to a vibration of the flow meter (5) at a substantially resonant frequency.

A filter used in a stiffness calculation is adjusted if the gain decay variable is outside the predetermined range.
