This paper deals with the outlet flow velocity measuring methods of a deodorizing device under development. In a normal state, the flow velocity vector has not one direction but various directions. So we can’t obtain the accurate flow rate. Then two measuring methods are examined to obtain more accurate flow rate. One is the experimental method in which a vinyl chloride cylinder is connected to the outlet of the deodorizer to guide the air passing through the filter to the cylinder (Cylinder experiment). The other method is that all the air passing through the deodorizing devise is gathered and stored in a bag (Bag experiment). Comparing the results mentioned above, the measured values of the bag experiment were lower than those of cylinder experiment. Therefore, in order to improve the measurement accuracy of the bag experiment, we conducted an experiment considering back pressure. As a result, the both results are agreement with each other.
