Abstract

PURPOSE:To generate Carman vortexes having an excellent resolution by arranging Carman vortex generating plates at a preset spacing at the back of a Carman vortex generating element lever. CONSTITUTION:A vortex generating element lever 6 of a triangle having an acute vertex angle theta is arranged upwatream of a pipe to prevent waves in parallel with a vertex generating element plates 5 from being generated. The element plates 5 having a width d are arranged such that the spacing t from the lever 6 satisfies the relationship of t=0.1d to 0.9d. Likewise, vortex generating plates 5', 5'' and so on are consecutively arranged. Then, Carman vortexes separated satisfactorily can be generated without being influenced by the variations in the flow speed and rate of a fluid. As a result, if the Carman vortexes having an excellent resolution are counted through Carman vortex detecting means 4, the flow rate or the like can be metered in high accuracy.
