FIELD: current supply to load.
SUBSTANCE: device has current source, first through fourth switches, and control unit. Method for feeding ac current to excitation unit of Coriolis flowmeter by means of proposed device includes control of ac current amplitude using current source, reception of feedback signal corresponding to at least one signal from strain sensors, control of first and second switches using feedback signal for feeding ac current of first polarity, and control of third and fourth switches using feedback signal for feeding ac current of second polarity.
EFFECT: reduced cost and simplified design of device.
