Coriolis mass flowmeter and node element

A node element for use in a Coriolis mass flowmeter having at least one measuring tube, having at least one oscillation generator and at least two oscillation sensors and having at least two node elements, wherein the at least one oscillation generator excites the measuring tube to oscillation during operation, wherein the at least two node elements define the oscillation range and wherein at least one node element has at least one stiffening element, the node element comprising:

• a body to which the at least one stiffening element is connected and having configuration adapted for being arranged on the measuring tube in such a manner that the at least one stiffening element increases the stiffness of the measuring tube with respect to the 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,
• wherein the first stiffening element has at least two separately acting components or at least two separate components.
