Abstract
A measuring system includes a vibration-type transducer including a flow tube and electronics coupled to the transducer for controlling the transducer and evaluating vibration measurement signals from the transducer, which includes a vibration exciter positioned and configured such that a drive offset between a drive cross-sectional area of the tube and a predefined reference cross-sectional area of the tube is no more than 3 mm and/or less than 0.5% of a tube length, wherein a vibration node between two vibration antinodes of vibration movements of the tube in a second or higher order lies within the reference cross-sectional area, wherein the electronics are configured to feed a drive signal to the vibration exciter such that the tube performs forced mechanical vibrations, the drive signal including current components, which deviate from resonant frequencies of vibration modes of the tube by less than 1% and/or by less than 1 Hz.
