Abstract
A mass flow meter for flowing media that works on the Coriolis Principle has at least one essentially straight Coriolis pipeline carrying the flowing medium, with at least one oscillator acting on the Coriolis pipeline and with at least one transducer detecting Coriolis forces and/or Coriolis oscillations based on Coriolis forces. Measuring errors or mechanical damage due to temperature fluctuations and outside forces and torques are minimized or eliminated by providing a compensation cylinder, and arranging the Coriolis pipeline inside the compensation cylinder.
