double 90° bends (in plane and out of plane) on the performance of wafer cone flowmeters
with same beta ratio (β) of 0.77 but different half cone angles (α) of 30° and 45°. The
influence of these disturbances on the upstream and downstream axial velocity (u) profiles
are studied experimentally. The orientation effects, if any, are also studied experimentally.
The minimum upstream distances required to get a fully developed flow for these …
