Abstract
A spacer has an annular concave portion, at one end face, to accept a rectifier that rectifies fluid flowing through a flow channel in a flowmeter, a protruding annular convex portion, at the other end face, of a size to fit in the annular concave portion, and fixing means, on an outer surface, for fixing the spacer to a tube of the flow channel through engagement. A rectifier unit is temporarily assembled by integrating the spacer and the rectifier that are provided alternately in series in an axial direction into a tubular unit. It is thus possible to achieve efficient assembly, by which plural rectifiers are inserted and attached inside the tube through a single insertion operation. Moreover, it is possible to address a need for a reduction of rectifiers in size or a change to the specifications regarding the number of rectifiers to be provided.
