摘要: A flow indicator is disclosed and includes a horizontally disposed housing including a lower inlet port drawing in an air sample, an interior space passing the air sample, an upper outlet port exhausting the air sample, and a transparent window allowing visual observation of at least a portion of the interior space. The flow indicator also includes a floater disposed within the housing and moving vertically in response to the flow of the air sample to indicate a flow rate for the air sample, wherein the housing further comprises a plurality of rails protruding from an inner surface of the housing and extending vertically to guide movement of the floater.
