定义
A sight glass tube is a transparent cylindrical component installed on industrial vessels, tanks, or pipelines to provide direct visual observation of liquid levels, fluid color, clarity, and flow conditions. It serves as a simple, reliable monitoring device without requiring electrical power or complex instrumentation.
工作原理
Operates on the principle of communicating vessels - the liquid level inside the tube matches the level in the connected vessel due to hydrostatic pressure equilibrium. The transparent material allows light transmission for visual inspection.
材料
Borosilicate glass (temperature resistant)tempered glassacrylic/polycarbonate (for lower pressure/temperature applications)with stainless steel (304/316) or brass end fittings.
Length
100-2000 mm
Diameter
10-100 mm
Connection Type
Flanged, threaded, or clamped ends
Pressure Rating
Up to 10 bar
Temperature Range
-20°C to 200°C
标准
ISO 3585DIN 7080DIN 7081
