ABSTRACT:
The invention concerns a mass flow meter for flowing media that works on the Coriolis Principle, with at least one Coriolis line carrying the flowing medium, at least one oscillator exciting the Coriolis line, at least two transducers detecting Coriolis vibrations based on Coriolis forces and a control unit controlling the oscillator and evaluating the measurement signals from the transducers, wherein the oscillator excites the Coriolis line with an excitation power and wherein a generator is provided that supplies the excitation power to the oscillator. The mass flow meter is characterized by the fact that the excitation power of the generator can be adjusted during operation, so that the amplitudes of the excitation oscillation of the Coriolis line can be adjusted to the most optimal value possible.
