ABSTRACT:
A swirler for a fluid flowmeter comprises a plurality of axially and circumferentially overlapping swirl blades within a flow conduit which impart a swirling motion to fluid passing therethrough. The swirler is constructed of a first element containing selected ones of said blades which are circumferentially non-overlapping and a second element containing the remaining blades which are also circumferentially non-overlapping; the two elements are assembled so as to bring the blades of each element into overlapping relationship with those of the other element.
