SS 304/316 Double Window Sight Glass – Continuous Visual Monitoring for Industrial Piping Systems

Monitoring fluid flow, clarity, color changes, and bubble formation in chemical, pharmaceutical, oil & gas, and water processing pipelines requires transparent inline inspection devices. The SS 304/316 Double Window Sight Glass manufactured by FlowBiz Exports provides 360-degree inline visibility through two opposing high-strength glass windows, allowing operators to safely monitor fluid movement without interrupting process flow.

Constructed from investment cast or fabricated SS304 / SS316 stainless steel with heavy-duty flanged ends, this double window sight flow indicator is fitted with toughened borosilicate glass discs protected by chemically resistant PTFE or graphite cushion gaskets. Available with optional drip lips, flappers, or rotary impellers, the FlowBiz Double Window Sight Glass ensures reliable, clear visual tracking under high thermal and chemical exposure conditions.
