Sight Glasses & Flow Indicators
Sight glasses and flow indicators for visual process inspection
Nemrex Industries supplies sight glasses and flow indicators for visual inspection of process lines and vessels. The range covers tank viewing windows, double-window flow indicators, tubular and full-view sight glasses, and rotary indicator configurations for industrial equipment.
Body-material options include stainless steel, carbon steel, alloy steel and other specified alloys. Glass, gasket, connection and mounting details depend on the selected configuration and process conditions. Tank windows provide a vessel viewing point, while inline indicators allow observation through a dedicated section of pipework.
Review the product families and technical details below to compare viewing arrangements, body grades, glass materials and connection types. For a complete assembly or replacement component, send the size, drawing, body and glass requirements, operating conditions and quantity. Mating dimensions help identify the correct configuration for an existing installation.
