    • A method for operating a mass flowmeter that employs the Coriolis principle and through which flows a medium, wherein the mass flowmeter incorporates a measuring tube that can be stimulated to oscillate, the measuring tube is stimulated to oscillate at a minimum of two mutually different frequencies and/or in at least two mutually different natural oscillating modes, and the resulting oscillations of the measuring tube are recorded. The density of the medium flowing through the measuring tube is determined by evaluating the acquired oscillations of the measuring tube on the basis of a physical-mathematical model for the dynamics of the mass flowmeter. In this fashion, highly accurate measurements are obtained for determining the density of the medium flowing through the measuring tube.
    • 一种用于操作质量流量计的方法,该质量流量计采用科里奥利原理并通过其流动介质,其中质量流量计包括可被刺激振荡的测量管,测量管被刺激以至少两个相互不同的频率振荡, /或至少两种相互不同的自然振荡模式,并记录测量管的所得振荡。 流经测量管的介质的密度通过基于用于质量流量计的动力学的物理数学模型评估测量管的获取的振荡来确定。 以这种方式,获得用于确定流过测量管的介质的密度的高精度测量。
