Abstract
A method for determining the gas portion in the medium flowing through a Coriolis mass flowmeter, wherein the Coriolis mass flowmeter has at least one measuring tube, at least one oscillation generator, at least two oscillation sensors and at least one control and evaluation unit, wherein the method is characterized in that the density value ρ100 of the gas-free medium is determined in a ρ100 step, that the density value ρmess of the medium flowing through the measuring tube is measured in a ρmess step, that a quantity GVQ for the gas portion of the medium flowing through the measuring tube is calculated in a GVQ step with the density value ρ100 and the density value ρmess, and that the quantity GVQ is output for the gas portion of the medium flowing through the measuring tube.
