Whether tubular, reflex, or transparent, all sight glasses have common problems associated with visibility, maintenance, safety, etc.

Before and after

 

	The Magtech Advantage	Sight Glasses
Visibility	Continuous, Highly Visible - No liquid inside indicator	Coating, plating, or etching; colorless liquids unreadable; No continuous  visibility due to  segmented  construction
Installation - Start-up	Simplified engineering design;(custom built to length of vessel), no segments less piping and field fabrication; Easier start-up, no torquing or retorqueing to stop leaks	Segmented construction required with extensive piping & bridles, valves, extra nozzles, etc.; Torquing of bolts required for each section of glass
Maintenance	Easy blow-down or flush of gauge chamber; No disassembly required, No spare parts	Regular cleaning requiring dismount and retorque; high temp and pressure increase downtime;spare parts required:gaskets, glass, etc.
Safety - Environmental	Fewer potential leak paths for fugitive emissions; No hazardous liquids behind glass; No glass  under high pressure or temperature causing risk to personnel	Numerous leak paths; glass breakage; release or spills of hazardous material
