Abstract
A method for determining the viscosity of a medium with a Coriolis mass flowmeter, wherein the Coriolis mass flowmeter has at least two measuring tubes that medium can flow through and a measuring device, wherein the measuring device has at least two actuator assemblies, wherein a measuring tube plane is defined by the measuring tube central axis and wherein the actuator assemblies are arranged on both sides of the measuring tube plane and outside of the measuring tube plane. Elaborate constructional measures for the Coriolis mass flowmeter are avoided by the measuring tubes being excited with a measuring device to at least oppositely directed torsion oscillation (and optionally additionally to plane oscillation) with the actuator assemblies being alternately actuated with opposing effective directions so that at least the viscosity of the medium is determined by evaluation of values from the measuring device.
