Abstract
PURPOSE:To eliminate the need for providing extra bypass lines to the outside part of a conduit, reduce size and simplify construction by providing a correcting column which is disposed in parallel with a vortex generating column on the upper stream side of the vortex generating column and can correct the number of generation of Karman vortexes. CONSTITUTION:On the upper stream side of a vortex generating column 2, and on the down stream of a flow regulating body 9, a correcting column 12 for the number of vortex generation of width narrower than the column 2 is provided in parallel with said column 2. If with such constitution gaseous flow flows into a conduit 1, a post flow area 13 slower than the average velocity of flow in the conduit is formed behind the column 12. Thereby, the vortex frequency of the case when there is the correcting column is made smaller as compared to the case when there is no column 12. Hence, the number of vortex generation is corrected without providing any extra bypass line to the outside part of the conduit, and the vortex current meter is made small in size and simple in construction.
