  • Coriolis flowmeter having a cross-sectional area of channels of the manifolds enabling a reduction in pressure loss
    Patent number: 9506793
    Abstract: Provided is a Coriolis flowmeter capable of achieving suppression of a pressure loss of a manifold and the like. A channel (15) of a manifold (8) includes a pipe-side opening portion (16), tube-side opening portions (17), and a channel branching portion (18) as shaping portions therefor, and the channel sectional area in a range of from the channel branching portion (18) toward the tube-side opening portions (17) is linearly decreased. A branching wall tip end (20) of a branching wall (19) extending from a position of the channel branching portion (18) to the other end of a manifold body (12) is arranged at the channel branching portion (18). The sectional shape of the channel (15) is a circular shape at a position of the pipe-side opening portion (16), and is changed to D-shapes at the position of the channel branching portion (18) by the branching wall tip end (20).
