Title: CORIOLIS FLOWMETER
Abstract:
The purpose of the present invention is to provide a coriolis flowmeter enabling, for example, reduction in pressure loss in a manifold. As the shaped portions of a channel (15) of a manifold (8), provided are a pipe-side opening portion (16), a tube-side opening portion (17), and a channel branching portion (18). The cross-sectional area of channels from the channel branching portion (18) to the tube-side opening portion (17) is linearly reduced. At the channel branching portion (18), disposed is a branching wall tip (20) of a branching wall (19) that extends from the channel branching portion to the end of a manifold body (12). The cross sectional shape of the channel (15) has a circular shape at the pipe-side opening portion (16) position, and at the channel branching portion (18) position, the cross sectional shape is changed to a D-shape by the branching wall tip (20).
