Patent ID: 7726202

Claim:
A tertiary mode vibration type Coriolis flowmeter comprising: a flow tube shaped to lie in a plane, said flow tube having a substantially elliptical loop-shaped body part and a pair of parallel leg parts connected to said substantially elliptical loop-shaped body part so as to form a T-shaped configuration in plan view, said leg parts being continuous with respective end parts of said substantially elliptical loop-shaped body part and configured to be deflected in a direction substantially orthogonal to a vibrating direction of said end parts and to an outside of said end parts, said leg parts each having a respective fixed end part for supporting said flow tube; a drive device for driving said flow tube by a bending vibration in a tertiary mode; a pair of vibration detection sensors for detecting a phase difference in proportion to a Coriolis force acting on said flow tube; a casing having a structure resistant to bending and torsion, said flow tube and said drive device being accommodated within said casing; and a stationary member in said casing and oriented so as to be parallel to said plane of said flow tube, a part of said stationary member being fixed to said casing; wherein said fixed end part of each of said leg parts of said flow tube is supported and fixed at an inlet port side and an outlet port side by support portions mounted to said stationary member.
