Fluid mechanical optimization of a DN25 vortex flow meter with novel vortex detection

In the present investigation, a new design vortex flow meter with novel pressure detection chamber has been optimized and investigated numerically as well as experimentally. Instead of implementing the standard configuration with paddle for vortex detection, a pressure chamber of optimized size and position has been investigated, allowing much higher temperatures of the metered fluid. Whereas the standard design is limited to 240 °C, the new design allows temperature in access of 500 °C. The present paper describes the results of numerical simulation of the corresponding high temperature flow field.
