Noris Armaturen – Technical profile of a sight flow indicator, tank sight glass and strainer manufacturer

Noris Armaturen is a German manufacturer of visual flow indication and pipeline protection equipment. Its range includes sight flow indicators, tank sight glass fittings, Y strainers, basket strainers, accessories, glass discs, gaskets and lighting units.

The products represented through Philippopoulos S.A. are mainly:

• double-window sight flow indicators,
• single-window flow indicators,
• flow indicators with flap, spinner or ball,
• high-pressure sight glasses,
• DIN and ANSI flanged versions,
• threaded and welded versions,
• tank sight glasses,
• Y strainers.

Sight flow indicators are used for local visual confirmation of flow, filling, colour, bubbles, foaming or suspended solids. They are not flowmeters and do not replace calibrated measurement instruments. Their role is direct field observation by operators or maintenance personnel.

Double-window indicators allow observation through the process line. Versions with flap, spinner or ball are useful when the medium is transparent and flow movement is not obvious. High-pressure versions must be selected according to pressure, temperature, glass type and sealing arrangement.

Tank sight glasses are installed on vessels and tanks for local visual inspection. In pressure vessels, they must be treated as part of the pressure boundary. Material, gasket, glass, pressure, temperature and maintenance method must be verified.

Y strainers are used to protect pumps, control valves, meters and downstream equipment from solids, welding debris, rust or commissioning particles. Selection requires mesh size, pressure drop, access for cleaning, drain arrangement and body material.

Noris products are relevant for process engineers, maintenance departments, steam specialists and plant operators requiring simple, mechanical visual indication and protection of industrial piping systems.
