Product Description

sight glass flow indicator

A view-through flow indicator has two opposing windows so that an operator can see the intervening flow of fluid lighted from behind. This design is suited for ANSI pressure classes, high temperature, and harsh fluid applications.

Also called 360° view, a full view flow indicator passes fluid through a glass cylinder that is visible from all angles. It is ideal for the observation of process fluid for clarity, color, foam, and other conditions, and for the presence of moisture. Depending on the model it may or may not be suited for high temperatures or pressures.

Most of our sight flow indicators are available with windows made of either standard soda lime glass (for temperatures below 300 F) or borosilicate glass (for temperatures between 300-500 F.)

Borosilicate glass is more resistant to thermal shock and caustic than soda lime glass, and should be specified in areas where hot equipment may experience washdowns with cool water or corrosive chemicals.

Quartz or sapphire glass is recommended for temperatures greater than 500 F, such as in high temperature steam applications.

Glass can come as a conventional glass disc or as a glass disc fused to a metal ring during manufacturing. Fused sight glass windows, such as our Metaglas® and Metaclamp® brands, hold the glass in concentric compression that makes the glass resistant to bending stresses that would otherwise cause cracks or failure. They are preferred when high pressure ratings, impact resistance, thermal shock resistance, and high safety margins are desired.

Borosilicate glass tubing and rod, available in varying types of inner and outer profile, has more advantages:
High Resistance to Thermal Shock
High Hydrolytic Resistance
High Chemical Resistance
Lighting: Flameproof light fittings others
Gifts: Decoration/grappa bottles Candlesticks Lanterns Others
Interior Decoration: Towel rails
