FIELD: electricity.
SUBSTANCE: system for generation of a driving signal in a vibration metering device, included into a Coriolis acceleration flow meter, comprises at least one pipeline (103A), at least one drive (104), at least one sensor (105), one or several electronic devices (20), configured to receive signals from sensors and including at least two accessible driving circuits (C1, C2, C3, CN). Each driving circuit modifies a signal of sensors for generation of a driving signal, including a differing frequency and a driving mode of vibration in a single pipeline (103A). At the same time electronic devices (20) include a selector (75) of a driving circuit designed for selection of a driving circuit for processing of signals of sensors with a selected driving circuit for generation of a driving signal and for provision of a driving signal to the appropriate drive (104). Each driving circuit (C1, C2, C3, CN) modifies signals of sensors so that it amplifies specific driving frequency and suppresses other driving frequencies. The specified system realises the appropriate method of driving signal generation.
EFFECT: invention makes it possible to optimise operation of a Coriolis acceleration flow meter for different conditions of operation specified by different physical parameters of a controlled fluid medium.
