<p>The method involves generating orthogonal projection components of response signals (yi-t). A value is determined with a part of changing portions of the components, where the value corresponds to resonance frequency of a resonance measuring system (1) i.e. Coriolis mass flow rate measuring device. Another value is determined with a part of same parts of the components, where the latter value corresponds to the resonance frequency. The two values are used for excitation of the system to an eigen form corresponding to the resonance frequency with a control in a control loop.</p> |
