High Accuracy Volume Flow Rate Measurement Using Vortex Counting [PDF]

open access: yes, 2013
A prototype device for measuring the volumetric flow-rate by counting vortices has been designed and realized. It consists of a square-section pipe in which are placed a two-dimensional bluff body and a strain gauge force sensor.
