ABSTRACT:
A tertiary mode vibration type Coriolis flowmeter includes a flow tube, a drive device driving the flow tube, and a pair of vibration detecting sensors detecting a phase difference in proportion to a Colioris force acting on the flow tube. The drive device drives the flow tube by bending vibration in a tertiary mode. The flow tube further comprises an approximately loop-shaped body part. A pair of parallel leg parts deflected in a direction approximately orthogonal to the vibrating direction of both end parts of the body part, namely, to the outside of the both end parts are formed continuously with the both end parts of the body part. Fixed end parts supporting the flow tube are formed at the leg parts.
