Abstract

PURPOSE:To simplify a manufacturing stage and reduce manufacturing cost by forming a cylindrical body in a simple shape which is realized by cutting treatment, plate work, welding connection, etc. CONSTITUTION:A cylindrical body 2 which has a circularly sectioned flow passage has the same diameter with a flow cirridor (diffusion barrel) for supplying air, sent from a blower, to a measuring barrel 1 for a wind channel having a squarely sectioned flow passage. One side part 2a of the cylindrical body 2 forms the downstream side of the fluid corridor 3 and at the other side part 2b, a deformed contract vein barrel is formed. The sectional shape of the deformed contreat vein barrel 13, consisting of segments 14 of cover bodies 12 and arc parts 15 of the cylindrical body 2, is symmetric with respect to axis, and the segments 14 of the cover bodies 12 are expanded form the fluid corridor 3 to the downstream side. A contracted vein barrel 16 in the same shape is provided successively to the bottom part 12a of the deformed contract vein barrel 13.
