These
gauges are designed for less demanding process conditions
that maximize the mechanical and economical advantages of
ductile iron covers.
These gauges are not recom- mended for Steam/Water
applications. (See Page 39).
Model 479 Reflex - has a single vision slot on one
side of the chamber in which light can enter to determine
liquid level. Above the liquid level, glass prisms reflect
the surrounding light giving typically a silvery appearance.
Below the level, the liquid fills the prisms causing the glass
to become relatively transparent giving a typically dark appearance.
Model 489 Transparent - has a vision
slot on both sides of the chamber allowing light to enter
the gauge opposite the observer so that the level or the liquid
and its characteristics can be seen.
