These
gauges are designed for the most common process conditions
and can be used for Steam/Water applications. (See Page 39).
High pressure gauges are available in Model 481 Reflex and
Model 491 Transparent. Illuminators and Frost Proof Extentions
are also available.
Model 480 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 490 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.
