Abstract
A mass flowmeter for flowing media, which operates according to the Coriolis principle, has a preferably cylindrical housing, at least one preferably essentially straight Coriolis measuring tube located within the housing and connected at both of its ends to the housing, a preferably cylindrical bridge located on the Coriolis measuring tube, at least one oscillation generator acting on the Coriolis measuring tube, and at least one sensor detecting Coriolis forces and/or Coriolis oscillations based on Coriolis forces, the bridge being located symmetrically and designed symmetrically with respect to the mid-point of the Coriolis measuring tube, wherein the midpoint of the Coriolis measuring tube is defined with reference to the ends of the Coriolis measuring tube connected to the housing, and the oscillation generator and the sensor being operative between the Coriolis measuring tube and the bridge, The flowmeter is characterized by the fact that the bridge is provided with a balancing system located essentially symmetrically and designed symmetrically with respect to the mid-point of the Coriolis measuring tube.
