PENBERTHY SERIES H 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 gage is handled, installed or

used and Emerson cannot and does not guarantee

that a gage is suitable for or compatible with the

user's specific application.

WARNING

Contained fluids may be pressurized and can

unexpectedly exit vessel connections 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.

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 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 view 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 high pressure 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.

3 AVAILABLE MODELS

Penberthy high pressure (Series H) liquid level

gages are designed for applications other

than steam/water, requiring a pressure rating

higher than that of Penberthy Series L or M

liquid level gages.
