Abstract
A measuring system comprises a measuring transducer which includes: a transducer housing with an inlet-side flow divider having exactly four, mutually spaced flow openings and an outlet-side housing end having exactly four, mutually spaced flow openings; four measuring tubes connected to the flow dividers for guiding flowing medium along flow paths connected in parallel; an electromechanical, exciter mechanism for producing and/or maintaining mechanical oscillations of the four measuring tubes; as well as a vibration sensor arrangement reacting to vibrations of the measuring tubes for producing oscillation measurement signals representing vibrations of the measuring tubes. Transmitter electronics includes a driver circuit for the exciter mechanism, and a measuring circuit. The measuring circuit of the measuring system of the invention corrects a change of at least one characteristic variable of the oscillation measurement signals delivered from the measuring transducer.
