Sight Flow Indicators provide a window into piping.  The process flow stream can be monitored by observation through the glass window.  Special mechanisms can be mounted in most sight flow indicator models to enhance visibility when observing a liquid.  Penberthy's four basic indicator types are Plain, Flapper, Rotator, and Drip Tube.
