ABSTRACT:
Device for measuring a mass flow according to the Coriolis principle comprises impeller driven at a constant speed, on which the flow of materials is fed, redirected and accelerated, and whereby the torque of the impeller is measured. The impeller is suspended on a torsion spring bar, which is arranged within a sleeve shaft. The torsion spring bar drives the impeller. There is at least one sensor to measure the angular shift between the powering sleeve shaft and the impeller.
