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.
Claims19
A mass flow meter for flowing media that works on the Coriolis Principle, with at least one basically straight Coriolis tube having opposite ends and carrying the flowing medium, at least one oscillator acting on the Coriolis tube, at least one transducer detecting Coriolis forces or Coriolis oscillations based on Coriolis forces and a support tube having opposite ends, the Coriolis tube being inside the support tube, and the Coriolis tube and the support tube being connected to one another so as to prevent relative axial movement, the improvement wherein the Coriolis tube (1) and the support tube (6) are made of materials with substantially the same coefficients of thermal expansion.
