A fractional flow indicator system by which flow in a fluid dispensing conduit is visually indicated using an improved fractional flow diverting element which utilizes a venturi effect rather than a check valve to create a fractional flow pressure differential to induce a fractional fluid flow through a flow indicator. The flow diverting element of the present invention has no moving parts, is easy and relatively inexpensive to manufacture, and does not restrict or reduce the pressure of the main fluid stream flowing therethrough. In accordance with the preferred embodiment, the flow diverting element is constructed from standard elbow components and a short length of copper tubing. The flow indicator system further includes an improved flow indicator having a compact construction with few working parts, which is easy to manufacture, less expensive to produce, and which provides a longer service life than conventional indicators. In particular, the flow indicator of the present invention does not include a multi-part pedestal, a precisely machined diverting nozzle, and a corresponding precisely machined port.
