PURPOSE:To enable the measurement of the low speed of a running fluid as well, by providing projections at a joining point of the inner walls of pipelines, and thereby improving the generation of vortexes. CONSTITUTION:A fluid to be measured which is introduced into a pair of introduction pipes 1 and 2 is straightened by straighteners 3 and 4 and then flows into the introduction pipes 1 and 2, and vortexes are generated by the walls of the pipes at the joining point thereof. For the stable and excellent generation of the vortexes, vortex stabilizing plates 7, 8 and 9 are provided. Moreover, the provision of projections 6 and 6' on the right and left sides of a pipe wall 5 improves the generation of the vortexes even in the area wherein the fluid flows at low speed. The frequency of generation of these vortexes is detected by vortex detectors 10 and 10'. |
