ABSTRACT:
A mass flow meter for flow media which works primarily on the Coriolis Principle has a pipe inlet, a straight pipe carrying the flow medium, a pipe outlet, an oscillation generator operating on the pipe and two transducers detecting preferably Coriolis forces and/or Coriolis oscillations affecting Coriolis forces. The flow meter has a relatively low natural frequency at a certain layout length or a relatively short layout length at a certain natural frequency, and in this way, the oscillation generator engages the pipe via an articulated arm so that the conduit is excited to torsional and bending vibrations.
