Abstract
A Coriolis mass flowmeter having at least one measuring tube with at least one oscillation generator and at least two oscillation sensors and having at least two node elements. The at least one oscillation generator excites the measuring tube to oscillation during operation. The at least two node elements define the oscillation range. At least one node element has at least one stiffening element. An effective separation of undesired interference oscillations of the measuring tube is achieved by the at least one stiffening element increasing the stiffness of the measuring tube with respect to oscillations orthogonal to the excitation mode and to the Coriolis mode so that, during operation, the oscillation frequency of the oscillation orthogonal to the excitation mode and to the Coriolis mode is greater than the oscillation frequency of the excitation mode, preferably greater than that of the Coriolis mode.
