ABSTRACT:
A mass flow meter for flow media which works on the Coriolis Principle, has a straight Coriolis pipe carrying the flow medium, an oscillator acting on the Coriolis pipe and two transducers detecting Coriolis forces and/or Coriolis oscillations based on Coriolis forces. The Coriolis pipe also carries mass bodies and is arranged inside of a housing or compensation cylinder. The mass flow meter improves the measurement result that can be obtained by increasing the stiffness of the Coriolis pipe for the excitation mode, preferably by including a reinforcing spring which acts on Coriolis pipe to increase the pipe stiffness for the excitation mode.
