Abstract
A vortex flowmeter including a shell member having an inlet and an outlet which are opened in the side wall thereof, a filter element provided in the shell member to define two, upper and lower, chambers inside the shell member and also isolate the inlet and the outlet from each other, a duct connected to the shell member in such a manner as to communicate with the outlet, and a vortex generating device provided inside the duct. A tubular projection is provided at the outlet in such a manner as to extend into the shell member, the projection being tapered toward the outlet, thereby correcting the flow of air flowing into the outlet so that the velocity distribution of air streams inside the duct becomes uniform.
