The rotameters for feeding and circulating system were calibrated with a wet meter
,4luaC) Lv1 Wieua IdLr w, Jeterniiuied by d bubble meter. iia; air dIow rate and the
correction factor of wet meter at standard conditions are calculated. The results are
illustrated in Figure 2 for the rotameter I (feeding system), and Figure 3 for the rotameter
II (circulating system), respectively. Their squared correlation coefficients (R2) are larger
than 0.99, Air flow of a bed reactor can be controlled with a large rotameter, which was
already calibrated. Its calibration curve is verified by using a roots meter (Model 5M125TC,
Dresser Systems, Inc,). Four tests are compared with the rotameter calibration curve (solid
line) as shown in Figure 4.
