A flowmeter of simplified construction in the form of a one-piece molded plastic body defining a float tube, tubular mounting studs at the base and the top of the float tube that also form the fluid connections to and from the tube, and a cylindrical valve chamber at the base of the float tube and aligned with the bore of the base stud, in which chamber a hollow cylindrical valve member is mounted by interengagement with a tubular connector extending through the base stud bore and having resilient legs that engage behind an annular flange in the valve member. A float is contained in the float tube, and the valve member defines a teardrop port for sensitive metering control of fluid supplied to the float tube, with a sealing ridge being formed about the valve member port, and sealing ridges formed about either end of the valve member, that are in firm sealing engagement with the body wall forming the valve member.
