PENBERTHY SERIES LC FLAT GLASS GAGES
INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
1 ABOUT THE MANUAL
This manual has been prepared as an aid and
guide for personnel involved in installation or
maintenance. All instructions must be read and
understood thoroughly before attempting any
installation, operation or maintenance.
SAFETY INSTRUCTIONS
Emerson does not have any control over the
manner in which its liquid level gage is handled,
installed or used and Emerson cannot and does
not warrant or guarantee that a liquid level gage
is suitable for or compatible with the user's
specific application.
WARNING
Contained fluids may be pressurized and can exit
vessel connections unexpectedly due to apparatus
or material failure. Safety glasses should be worn
when installing a liquid level gage. Failure to
follow instructions could result in serious physical
injury or property damage.
2 INTRODUCTION
Penberthy liquid level gages are used to allow
direct visualization of liquid level in vessels.
By peering through the glass, it is possible to
monitor color, clarity and level of a gas/liquid
interface. Gages are available in varying lengths
and configurations (end connect, side connect,
multiple sections, NPT or flange connections,
etc.). Visual indication can be enhanced by
using reflex glass or illuminators (accessory).
2.1 System description
Penberthy Series LC gages comprise six
basic components. Each component may vary
slightly, depending on the desired physical and
mechanical properties for the gage. Use the
exploded parts views in Section 11 as additional
reference material.
Chamber: provides a pressure-retaining
metallic channel for the liquid to enter and be
viewed. Slot(s) are machined into the chamber
to provide direct visualization of the process
fluid.
Gaskets: seal the gap and prevent leakage
between the chamber and the glass. Gaskets
are available in a variety of materials for
compatibility with the media in the gage.
Glass: allows for visual observation of the
process fluid in the chamber.
Cushion: acts as a protective buffer between
the glass and the cover. For proper sealing,
cushions must be as hard or harder than the
gasket material.
Cover: protects the glass assembly from
external hits and provides a flat, rigid surface
that is used to compress the gage assembly
evenly. The large chamber gage cover
resembles a football. It has significantly more
metal along the center of the sides to provide
more strength and resistance to high pressure
stresses.
Bolting: compresses the components between
the covers (transparent gages) or cover and
chamber (reflex gages).
Shield: (optional on transparent gages) used
to prevent the process media from contacting
the glass.
