    摘要: In one embodiment, a sight tube flowmeter is formed of a plurality of fluoropolymer components welded together to form a unitary flowmeter body. The components can comprise a PFA upright sight tube having two end portions, a flow conduit extending therethrough and two fitting portions that are uniquely welded onto each end of the sight tube, and a fluoropolymer float device movable to various positions within the flow conduit depending on the flow level of the fluid flowing therethrough. The float device can be of conventional design or for those flowmeter embodiments where low fluid flow rates are to be measured, an elongate float can be utilized. The floats and, in particular, a designated portion thereof, are visible through the sight tube to provide visual indication of the position, and thus the flow rate of fluid flowing through the flowmeter. In addition, alternative embodiments include the implementation of the unique sight tube and elongate float design in conventional flowmeters.
