Abstract
A method for determining a viscosity measurement value of a medium conducted within an oscillatory measuring tube includes exciting at least one oscillation mode of the measuring tube; determining a natural frequency of the oscillation mode; determining the density of the medium; determining the damping of the oscillation mode; and determining the viscosity measurement value depending on the density, the natural frequency, and the damping of the oscillation mode, wherein the viscosity measurement value is determined, depending on a specification of the type of medium, with a model corresponding to the specification.
