Description:
Model series DG04 sight glasses are distinguished by their
rugged construction and wide range of applications. They
feature 0.94", 1.18", or 1.97" / 24, 30, or 50 mm long transparent
cylinders made of acrylic, soda-lime or borosilicate
glass with very high wall thickness. These cylinders are
intended to be clamped between two existing flanges. Their
dimensions match those of the sealing face on the raised
area of the flange. This sizing makes support from a separate
metal housing unnecessary. In addition, this design
allows the flow to be viewed and monitored from any direction.
The flange bolts also offer additional protection against
mechanical damage.
The borosilicate glass version can be installed in devices
used with very caustic/corrosive liquids. They are insensitive
to contamination because the inner surface is constantly
being rinsed by the flowing liquid. In particular, the larger
nominal sizes are very cost effective solutions since they
only require the transparent cylinder and no metal housing
with flanges.
