Abstract

Method and measurement arrangement for measurement of air permeability in a felt 1. In the method the air stream produced via suction box 2 through the felt 1 is passed through a measurement channel 3a representing a measurement tube and the air flow in the measurement channel is measured by means of a Pitot tube 4 placed in it. The measurement device has a suction tube 3 positioned against the side of felt 1 facing away from suction box 2, to which the measurement channel 3a representing the suction tube 3 is connected. The Pitot tube 4 is mounted in the suction tube 3, to which a measuring device 5 is connected via a coupling part 4a and channels 6, 7 to measure the pressure produced by the air stream in the Pitot tube. <IMAGE>
