L.J. Star, Inc. publishes a white paper that provides technical guidance and advice for process operators who use sight flow indicators in process pipelines to provide a visual means of verifying liquid flow. The succinct “Guide to First Indication Flow Rates of Sight Flow Indicators” includes tables that show the flow velocity required for first indication for sight flow indicators available from L.J. Star (flapper and rotator style), as well as illustrate the required respective velocity for flapper and rotator style indicators, relative to pipe size.

The paper outlines the types of applications in which certain flow indicators may be applied as well as points to keep in mind when specifying a sight flow indicator, including direction of flow, characteristics of the process material, pipe size and directional orientation and window design. The white paper also offers some guidance on applications for visual flow meters and situations where certain types of flow indicators are not recommended.
