Abstract (en)
[origin: WO2020259762A1] The invention relates to a method for ascertaining a flow parameter of a medium, in particular the mass flow rate, using a Coriolis flow meter of a specified measurement device type and to a device which is suitable for said method. According to the method, the medium, which has a medium viscosity, flows through at least one measurement tube piece that is mechanically vibrated by a respective excitation signal, at least one measurement signal dependent on the flow parameter, in particular a phase shift, is ascertained in the vibration behavior of the respective measurement tube piece, and the flow parameter is determined from the at least one measurement signal while taking into consideration the dependency of the flow parameter on the medium viscosity, wherein a data field which is ascertained using an interpolation method, in particular a kriging method, and which indicates the dependency of the flow parameter on the medium viscosity is used in order to determine the flow parameter.
