The effects of tube bundle straightening vane location on orifice meter Cd and axial velocity profile have been investigated for nitrogen flow at a Reynolds number of 9*105 in a long (45 D), 4 inch diameter (100 mm) meter tube downstream of a 90° elbow. A 19 tube bundle straightening vane was modified to allow changing the vane to orifice distance, (x/D), without reassembling the meter tube. Results are presented for Cd variation for β=0.75 and 0.40, and for axial velocity profile as a function of x/D from 5 to 42.5.
