A flowmeter body (100) comprises a flow inlet (102), a flow passage (104) and a flow passage outlet (106). A shedder bar (108) is disposed in the flow passage (104). A sensor (110) couples to the flow passage. The sensor senses flow vortices (148) shed from the shedder bar. A flowmeter outlet surface (114) is joined to the flow passage outlet (106) and extends to an outer rim (116). The flowmeter outlet surface (114) includes an annular groove (118) positioned to interact with local vortices (120, 122) shed from the flow passage outlet.
