PURPOSE:To prevent the influence of disturbance upon a flow of fluid in a flow passage, and to improve measurement precision, by arranging a splitter vane on the fluid exit side of the 2nd pipe with a slight interval to the flow passage wall of the pipe. CONSTITUTION:A splitter vane 18 has its upstream-side edge more at the downstream side in the flow passage of the 2nd pipe 7 than the opening 14 of a flow passage 16, and also has its one flank 20 at slight distance from the flow passage wall of the pipe 7. Further, its downstream-side edge is provided a little bit more on the upstream side than the opening 15 of the passage 16 in the flow passage wall of the 1st pipe in such a way that one flank 20 faces the opening 15. Then, even if disturbance is generated on the upstream or downstream side of the flow passage, a flow of fluid specially near the fluid exit 9 of the pipe 7 is stabilized without the influence of the disturbance. |
