Abstract:
A mass flowmeter for flowing media, which operates according to the Coriolis principle, with a preferably cylindrical, in particular circular cylindrical, housing, with at least one preferably essentially straight Coriolis measuring tube located within the housing and connected at both of its ends to the housing, with a preferably cylindrical, in particular circular cylindrical, bridge located on the Coriolis measuring tube, with at least one oscillation generator acting on the Coriolis measuring tube, and with at least one sensor detecting Coriolis forces and/or Coriolis oscillations based on Coriolis forces, the bridge being symmetric 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, characterized by the fact that the bridge (3) is provided with a balancing system (4) which is symmetric with respect to the mid-point and consists of a balancing mass (5) and a balancing spring (6) capable of oscillation with respect to the bridge (3).
