Measuring system for use as compact Coriolis mass flow rate/vicosity measuring device to measure e.g. density of slurry flowing into process line, has measuring tubes executing diametrically opposed torsional vibrations in fundamental mode

摘要

The system (1) has an electromechanical exciter arrangement for proportionally converting electrical excitation power to torsional vibrations of two measuring tubes (18-1, 18-2). A middle tube segment of one of the measuring tube executes rotational vibrations around a torsional vibration axis, and a middle tube segment of the other measuring tube executes rotational vibrations around another torsional vibration axis and/or the measuring tubes execute diametrically opposed torsional vibrations in a torsional vibration fundamental mode consisting of a single loop.
