Patent ID: 7845241

Claim:
A Coriolis flow meter, comprising: a single flow tube comprising; an inlet section ( 312 ) and an outlet section ( 314 ) where the inlet section ( 312 ) and outlet sections ( 314 ) are axially aligned; a first bent section ( 316 ) attached to the inlet section ( 312 ) and a second bent section ( 318 ) attached to the outlet section ( 314 ); a connecting section ( 324 ) extending between the first bent section ( 316 ) and the second bent section ( 318 ) where the single flow tube is symmetrical about an axis of symmetry that intersects a center of the connecting section ( 324 ) and where the single flow tube is formed essentially in one plane; a torsion member ( 430 ) having a center section, a first end, and a second end where the first end is attached to the connecting section ( 324 ) of the single flow tube near the first bent section ( 316 ) and the second end is attached to the connecting section ( 324 ) of the single flow tube near the second bent section ( 318 ); a balance member ( 432 ) attached to the torsion member ( 430 ) and extending towards the center of the connecting section of the single flow tube and where the balance member ( 432 ) is generally perpendicular to the torsion member ( 430 ); and at least one drive bracket ( 438 ) attached to the balance member ( 432 ) where the at least one drive bracket ( 438 ) is configured to mount a drive device where the drive device is configured to apply a force against the single flow tube; wherein the first end and the second end of the torsion member ( 430 ) is configured to vibrate in-phase with the single flow tube and the center section of the torsion member ( 430 ) is configured to vibrate in the opposite phase with respect to the single flow tube thereby causing the torsion member to deform in torsion along a torsional vibration axis.
