The flow indicator is available in a variety of sizes, ranging from ½ to 12 inches, and is full-ANSI rated. All are available with indicators such as rotors, flappers and drip tubes.  The highly durable sightglass is made from tempered borosilicate glass, a material that wears very well under pressure, caustics and high temperature. This product may be requested in stainless, carbon or Teflon lined, and includes independently-bolted glass retainers.

Reliable and low-cost, this flow indicator enables the observation of the direction and rate of flow of liquid, powder or gas through pipelines. It also allows operators to observe the color and clarity of process fluids through the viewing window.
L.J. Star's Standard Visual Flow Indicator is available in flanged or threaded connections, both of which are ANSI-designed for 150 psi or 300 psi. The flow indicator may be ordered in a wide range of styles engineered to accommodate various mounting positions, fluid characteristics and flow rates. All L.J. Star flow indicators meet or exceed pressure and temperature ratings, which vary depending upon the sightglass design.
