method and device for massenstrombestimmung according to the coriolis principle

摘要

to increase the accuracy in the massenstrombestimmung of conveyed material, particularly a mehrphasenstroms from a bulk material and a gas, and the coriolis principle as a measure to determine the massenstroms is used, is proposed, the flow volume of the fu00f6rderfluid s, especially fu00f6rderluft,before entering the coriolis meu00dfrad to measure, and then the difference between the drive torque to the meu00dfrad identified gesamtmassenstrom material together with the fu00f6rderfluid and the flow volume of the fu00f6rderfluids separately to form. in a preferred implementation is in the fu00f6rderfluid - measuring device as the coriolis meu00dfrad trained.by the proposed method and the corresponding device is of the unberu00fccksichtigte fu00f6rderfluid - flow volume measure and in the determination of the massenstroms material into account, particularly at high throughputs of the meu00dfgenauigkei fu00f6rderluft t significantly increased.
