The balance bar (230) comprises a first side portion (231) having a hollow interior for receiving a flow tube (220), a central portion (233) having a hollow interior for receiving a flow tube (220), and a first side flexible portion (234) comprising at least one flexible coupler (250), the first side flexible portion (234) coupling the first side portion (231) with the central portion (233), wherein the first side portion (231) and the central portion (233) are both more rigid than the first side flexible portion (234).

A mode splitter (300) for a balance bar (150) of a Coriolis flow meter (100) is disclosed. The mode splitter (300) comprises a mass portion (302), and a first coupling portion (304a) coupled to the mass portion (302). The first coupling portion (304a) has a first stiffness in a drive direction (Y) and a second stiffness direction in an orthogonal direction (Z), and the orthogonal direction (Z) is orthogonal to both the drive direction (Y) and a longitudinal direction of the balance bar (150). The second stiffness is different than the first stiffness.

A flow dampener for dampening pulsation in a fluid flow includes a body shell, a flexible membrane, and two flow ports. The body shell has an interior surface and an elongate groove formed on the interior surface. The flexible membrane is sealed to the interior surface of the body shell and covers the elongate groove. In some embodiments, the flexible membrane is over-molded onto the body shell. The flexible membrane cooperates with the elongate groove to form an elongate flow path for the fluid flow. The flexible membrane has a thickness in a range from 0.5 mm to 6 mm. As the membrane is flexible, it vibrates as the fluid flows through the elongate flow path, absorbs kinetic energy in the fluid flow, and thereby dampens pulsation in the fluid flow.
