Abstract (en)

[origin: WO2021173132A1] A Coriolis flow meter may comprise a first flow tube having a first end and a second end. The first end may have a first reaction force, and the second end may have having a second reaction force. A second flow tube may be operably connected to the first flow tube. The second flow tube may have a first end and a second end. The first end may have a third reaction force, and the second end may have a fourth reaction force. A drive system may be operably connected to the first and second flow tubes. At least one balance mass may be operably attached the first flow tube or the second flow tube. The one balance mass may be sized and positioned to minimize one or more of the first reaction force, the second reaction force, the third reaction force, and the fourth reaction force.
