Flat glass gages provide direct observation of liquid level in a processvessel. The process liquid level and liquid characteristics can be observedthrough the glass as it rises and falls inthe gage chamber.
The six basic components of flat glassgages are as follows:
ChamberPressure retaining element which provides rigidity to the gage assemblyand a means to connect the gage toisolation gagecocks or other vessel connections.
Penberthy’s standard chambers have aflat gasket seat to allow for easyremoval of gasket residue and fragments. Because the chamber doesnot have a recessed face, the gasketmay be removed quickly with a flatblade.
Penberthy has an optional chamber witha recessed gasket seating surface tomeet customer requirements.
Slots are machined into Penberthy’stransparent gage chambers rather thancontinuous vision slots. These crossties between vision slots increase the
mechanical integrity along the length ofthe chamber.
The cross tie provides a higher strengthchamber due to the reduction of unsupported beam length. Chambers areavailable with PFA (Teflon®), PECTFE(Halar®), and PETFE (Tefzel®) lining.
ArmoredFlat GlassGages
GasketSeals the gap and prevents leakingbetween the glass and the chamber.
GlassContains the process liquid and providesthe viewing window to the process liquidlevel.
CushionProtects the glass from mechanical stresspoints by acting as a buffer between theglass and cover.
CoverProtects the glass from mechanicalimpact along the sides of the chamberand provides a compression surface forthe bolts/studs/nuts to hold the gasketand glass tightly against the chamber.
Bolts/Studs/NutsProperly torqued gage bolting applies auniform compressive load to the gageassembly for pressure retaining purposes.

Multiple SectionGagesTo meet visible glass lengths greaterthan Size 9 glass (12.625” [321 mm]),Penberthy stacks covers along thelength of the single chamber. Themaximum operating pressure andtemperature ordinarily determine thelargest glass size that can be used.
Vision slots are cut according to thesize of the glass used and thenumber of sections necessary tomeet the desired vision length orminimum center to center (vesselconnections). Support bracketsshould be attached to larger gages tosupport the weight of the gageassembly.
The maximum number of sections(covers) that can be used on a singlegage chamber is ten. If the requiredliquid level vision length extendsbeyond 139.750” [3550 mm], multiplesection gages may be bridled to astandpipe or alternately top-bottomside connected.
Gage ConnectionsEnd, side and back (typically reflexonly) connections can be machinedinto the gage chamber to provide endusers with desired center to center
distance and/or the optimum visionposition for liquid level viewing.Connections include NPT, BSP, ANSIflanged, DIN flanged and socketweld.

Reflex andTransparent GagesReflex gages have a single vision slotin which light can enter the gagechamber to determine liquid level.Above the liquid level, glass prismsreflect the surrounding light. Belowthe liquid level the liquid fills theprisms causing the glass to becomerelatively transparent.
Light striking the area of glass covered by transparent liquid isallowed to pass through to the interior of the gage along the entirelength of the covered prism. The lightis reflected from the back of thechamber to the observer. Typicallythe chamber appears dark. Anopaque liquid such as milk woulddirectly reflect the light at the surface of the prisms, where itappears as a solid column of white.
Light striking the area of the glassabove the liquid level experiencesinternal reflection. Internal reflectionwill occur when light attempts tomove from a medium having a givenindex of refraction to one having alower index of refraction.
When the light attempts to movefrom a higher index of refraction(glass – 1.47 index of refraction)to a lower index of refraction(air – 1.00 index of refraction
through the prism angle), it reflects ratherthan passes through to the back of thechamber. Except for a focused line of lightalong the apex of the prism, the surrounding light reflects back to theobserver appearing silvery.
The interface between the liquid andgas occurs where the silvery anddark/opaque area intersect.
Transparent gages have a vision slot onboth sides of the chamber. Light entersthe gage from the side opposite theobserver so that both the level of aliquid and its characteristics can be seen.For easier liquid observation in darkenvironments, illuminators are availablefor use with transparent gages.
Transparent gages may be used for interface applications.

Borosilicate glass is the most common type of optic material usedin Penberthy gages. Borosilicateglass offers good resistance to mostchemicals at temperatures at orbelow 600˚F [316˚C].
Penberthy uses tempered borosilicate glass in its gages toimprove thermal shock resistance.The tempering process involvesheating the glass to a glassy transition point and rapidly coolingthe glass to create compressivestress in the outer 1/6 of thickness.
Aluminosilicate glass has a higherviscosity and a lower thermalexpansion coefficient compared toborosilicate glass. Aluminosilicateglass is commonly used whereprocess temperatures are greaterthan 600˚F [316˚C] but are at orbelow 800˚F [427˚C].
Fused quartz is made from crystalline silica with few impurities(50 ppm by weight). The highesttemperature rating, 1000ºF [538ºC],is achieved by using quartz.
Materials other than quartz limita gage assembly’s maximumoperating temperature.
Penberthy offers quartz in its modelTH only. The physical properties ofquartz require an extremely flatseating surface. Flatness toleranceof gasket and cushion seating surfaces on chambers and coversmust be maintained to avoid torsional or point stresses on thequartz.
Shields (e.g., PCTFE, Mica) can beinstalled to prolong the life of transparent flat glass in corrosive orerosive environments such ashydrofluoric acid, sodium hydroxideor steam.

Borosilicate Glass, AluminosilicateGlass and Quartz
Armored GagesArmored flat glass gages give usersthe ability to visually inspect liquidcharacteristics (color, particulate,striations, turbulence) and monitor relative fill or drain rates in a variety ofapplications where vibration,temperature and/or pressure extremesrule out level technologies.
End users interested in establishing areliable, easy-to-understand level reference often use flat glass gages toverify electronic level device output atplant start-up or routine maintenance(especially pressure vessels).
Other distinct advantages:
• They require no electrical power.Level can be monitored in remotelocations where no power isavailable. In event of a power failure,the flat glass gage is not effected.
• They are not dependent on mostliquid properties. Multiple liquids canbe processed through the samevessel without concerns for density,surface turbulence, di-electric,conductivity, etc.
• They’re suitable for vacuumapplication.
• They provide a near-unlimited lengthof measure.
• They’re non-intrusive.

for direct mounting tovessel wall...For application involving high vibration,highly viscous liquids or liquids withconsiderable amounts of solids,Penberthy offers end users a flat orradius weld pad gage. Because thereare no nipples through which theprocess liquid enters the gage,clogging potential is eliminated.
When welding the gage to a vessel, it isextremely important to take properprecautions to prevent warpage of thechamber. Penberthy stronglyrecommends the use of an optionalsteel spacer for welding.
After welding, it is important to checkthe flatness of all glass seating surfacesas described in Penberthy’s Installation,Operation, and Maintenance manual.
All materials in weld pad gages conformto ASTM specifications. RMW and TMWgages can achieve pressures to 2000 psig[13790 kPa] @ 100˚F [38˚C] – when manufactured with size 1 glass– see table below.

for extraordinarypressure and vaporrequirements...The method of clamping and sealingthe glass differs from other gages inthat the glass does not experiencestress concentrations imposed bybolting. The glass becomes afloating member between two solidlybolted blocks of rigid plate.
The pressure activated seal principleprovides a self adjusting means ofmaintaining a tight joint betweenglass and liquid chamber. Thegasket system compensates formachining variations.
Because glass can take atremendous amount of evenly loadedcompression, the gage can withstandextremely demanding pressurerequirements.
All materials in TU gages conform toASTM specifications. TU gages canachieve pressures to 6000 psig[41370 kPa] @ 250˚F [121˚C].Pressure rating is not glass sizedependent. A higher temperaturerating 400˚F [204˚C] @ 6000 psig[41370 kPa] can be achieved byusing Viton®. Teflon® can achieve500˚F [260˚C] @ 6000 psig[41370 kPa].

After experiencing a problem onone of their offshore rigs, amajor oil company requested thatTyco initiate a research programto develop better corrosion protectionfor offshore gage glass. To assessthe relative strengths andweaknesses of various coatings andmaterials commonly used as“offshore protection,” we subjected anumber of our own gages as well ascompetitive models to an acceleratedcorrosion/weathering test (ASTMB117). While the tests wereperformed in a controlled laboratoryenvironment, the exposure to over2500 hours of heat and salt sprayprovided a corrosive environment thatwas judged to be comparable to twoyears of actual offshore use.
Above left is a Penberthy gage(figure 1) which was used offshore fortwo years in the Gulf of Mexico. Itwas prepared according to anindustry-accepted specification whichthe oil company had established forits offshore equipment. Badlycorroded and potentially dangerous,this gage establishes a benchmarkfor the kind of corrosion anddeterioration that typically occurs

Competitive comparison shows the need for concernin selecting a gage with “offshore” design
As important as coatings are in makinga gage corrosion-resistant, their valuecan be rendered useless if the glass isleft vulnerable to other types of damage. The total protection of gageglass is critical in complementing theeffectiveness of offshore coatings.
The Penberthy offshore gage design isunique in its ability to completely isolate the gage glass from abrasiveforces. This complete protection isimportant because even seemingly
minor abrasions can cause thetempered gage glass to lose mostof its pressure containing ability.
The following diagrams illustrate therelative vulnerability of the glass oncompetitive models.

lass Overview
during two years of actual offshoreuse. Corrosion on interior surfaceshas put stress on the glass, making itvulnerable to failure. Also, the heavilycorroded bolts cannot be retorqued inroutine maintenance.
As a result of these tests, Tycohas developed a unique three-partcoating, applied to the componentsbefore the gage is assembled, toprovide unprecedented gageprotection in offshore application.The Penberthy gage also includes avariety of unique design features tofurther extend gage life.
Durable coatings complement theeffectiveness of inorganic zinc
Polyurethane Top-Coat(2.5 to 3 mil)Its glossy tile-like finish dramatically upgradesthe weather resistance of the layered coatings.Provides excellent added protection fromchemicals and abrasion as well.
Epoxy Tie-Coat (4 to 8 mil)Epoxy polyamide complements the zinc primerby providing added abrasion resistance andprotection from weathering. Also provides aneffective base for the topcoat.
Inorganic Zinc Primer (2 to 3 mil)
This self-curing coating produces a tight bond toprepare surfaces and protects steel galvanically.Meets performance requirements ofANSI N 101.2-1972 and N 5.12-1974.
First, and prior to assembly, all metalparts are coated with a layer ofsacrificial inorganic zinc. Then, afterassembly, they are sprayed with anepoxy tie coat and urethane finish.
Nuts, bolts and washers are stainlesssteel to assure that they will never rustand that nuts can be periodicallyretorqued, as required. Washers,in turn, prevent the protectivecoatings on the cover from beingscraped off.
Attached with a durable silicone sealant,this strong clear polymethylmethacrylatepanel fully protects the glass front from flying sand and debris. Illuminators for offshore gages are always type 4x and thePMMA wedge is sealed the same as thePMMA gage glass protecting panel.
Gage cover extends the full depthof the glass and protects it laterally fromsandblasting and other abrasives fromnearby installation and maintenanceoperations.

for cost effectivelevel indication...Penberthy Tubular Glass Gages areused to register liquid levels in low tomedium pressure applications. Theyare externally mounted to the vesseland use tubular glass to providedirect visual verification of the liquidlevel present. The transparent glassalso provides an excellent means tooptically inspect fluid characteristics.
Liquid enters the gage through thelower tank connection. The meniscuspresent in the glass tube correspondsto the liquid level in the tank.Available accessories allow you tocustomize each gage to your specificapplication requirements. Theseoptions can also provide enhancedlevel indication and protection for thetubular glass.
ProtectorsTubular glass is susceptible toaccidental breakage. To counteractthis condition, Penberthy offers avariety of protectors. Theseprotectors prevent damage to theglass, but do not restrict levelindication capability. In some casesthe protector actually enhances it.Protectors can be adapted to fit mostmajor manufacturers’ gagecocks.
Guard Rods – Two or four metallicrods placed next to the glass tube.
Plastic or Wire Glass – A transparentbox surrounding the tubular glassconstructed from either clear plastic orwire glass.
Sheet Metal – Two pieces of sheetmetal formed to protect both sides ofthe tubular glass. The front and backare left open to facilitate easy viewing.
Refractive – An extruded aluminumchannel with your choice of either apolymer or glass cover. The interioris a white anodized finish with 45ºangle red stripes on the back wall. As
Tubular Glass Gages
the gage fills, liquid passes in front ofthe stripes. The refractive nature ofthe liquid changes the stripe angleshowing the highly visible contrastbetween liquid presence andabsence.
If water is the liquid used, the stripesbecome horizontal. Liquids with arefractive index less than water willalter the angle less, higher indexeswill alter the angles more. Therefractive protector is designed for usewith standard tubular glass.
Internal TubesA stainless steel internal heating orcooling tube that passes through thelength of the tubular glass can be usedin conjunction with an offset patterngagecock and high pressure glass.
Glass UnionIntended for use in gages over 48” inheight. It allows you to join two piecesof glass within the same gage. Thisincreases the length of the gage, yetmaintains the same pressure/temperature rating as the individualpieces of glass. Glass unions shouldbe used in conjunction with therefractive protector to providemechanical stability.

The Graph-a-BondTMgasket: superior strength andbetter adhesion
Frustrated with GRAFOIL® gasket folding,flecking, denting and slipping? Penberthyhas the answer – a graphite compositegasket that provides both superior strengthto resist gasket deformation and better surface adhesion than commonly usedgraphite gaskets. (Concept is covered by US Pat# 5,895,058, otherpatents and proprietary data may pertain).
Penberthy has combined the grip of fibrousgasketing with the superior sealing andphysical attributes of graphite to create aGraph-a-BondTM gasket. It provides:
• Excellent chemical resistance• Efficient conduction of thermal energy• Stability at high temperatures• Extremely low microporosity (leakage)• “Springback” resilience to conform to
curved and flat surfaces• Reduced gasket blow-out
Penberthy has also attached a fibrous gasket (elastomeric binder) to the otherwise exposed graphite material tonegate its natural lubricity and difficulty inhandling. As a result, handling Penberthy’sGraph-a-Bond gasket is much easier thanconventional graphite gaskets, helping toeliminate the possibility of damage duringgage assembly. The fibrous laminate alsogives the graphite a higher degree ofstiffness to resist deformation or bendingbetter than graphite gaskets with polyesteror metal inserts.
The Penberthy gasket is also ideal to retrofit onto aged chambers that haveexperienced rebuilds over the years andmay leak if conventional graphite gaskets are used. Note that the Penberthygasket fits any manufacturer’s standard-size flat glass gage. Gasket material can bemanufactured for use with other fittingsincluding flanges.
Cross-section of gasket, showingfibrous laminate providingstiffness and better handlingcharacteristics
The laminate bonding is crucial tothe success of this gasket form. Itis a very thin combination of acrylonitrile and phenolic polymers.The acrylonitrile, a thermoplastic,provides the initial bonding at relatively low temperatures andduring the heated pressure rollerinitial laminating phase. As temperature is increased duringapplication, the acrylonitrile carbonizes and the phenolic, a thermosetting polymer, becomesthe bonding agent. At extreme temperatures, the entire seal(binders, adhesives, etc.) turns carbonaceous with high bondingstrength to the sealed members(the so-called “frying-on”). Oncecarbonaceous an effective seal canbe maintained until such time asexcessive mechanical shifting ofthe elements (due to pipe stresses,thermally induced movement, etc.)occurs.

A Solution to UnionConnection Leakage . . . . . Penberthy now offers a metallic (AISI 304 stainless steel) spiralwound graphite gasket that fits in a precision machined groove inthe union face of the gagecock body.
This gasket will compensate for any small misaligned plumbingconnections and will provide a tight and effective seal. When experiencing larger misalignment problems, consider a sphericalunion connection.
This option will virtually eliminate leaks, reduce maintenance costand will add to the overall safety of the installation.
For periodic maintenance, simply replace the gasket pre-form.
If a gasket is needed on the gage connection only, use model number X22. For a vessel connection gasket only,use model nunber X21 or X31. For gasketed gage and vessel connections, use model number X23.
Examples:Model 423 = 400 series gagecock with gasketed union gage and vessel connections.
Model 331 = 300 series gagecock with a rigid gage connection and a gasketed union vessel connection.

Offset and straightpattern designs forflat glass and tubularglass gagesPenberthy offers offset and straightpattern gagecocks that isolate the gagechamber from the liquid contents ofthe vessel. Gagecock seat leakage isClass I per ISA RP39.6, FCI 70-2 (formerlyASME B16. 105) and/or IEC 60534-4.
Offset gagecocks have an advantageof permitting the inside of the gageglass to be cleaned easily with aminimum of disassembly. Byremoving the vent and drain plugs(or other connection), a straightpassage through the gage chamberis opened. A brush can be insertedthrough the gagecock vent and drainfor glass cleaning.
To prevent rapid loss of fluid in theevent of accidental glass breakage,Penberthy supplies its gagecocks withautomatic ball check shut-off. Shouldthe glass break, the pressure dropcauses the ball checks to seat toprevent loss of tank contents.
To unseat these ball checks duringthe liquid level readings, the tip of thegagecock stem has an extension thatpushes the ball away from its seatwhile allowing the gage column to fillas liquid contents pass around theball. Stainless steel retainers preventreverse seating of balls or loss ofballs during installation.
Both upper and lower gagecocks in eachset are equipped with horizontal ballchecks. Balls are located on the vesselside of the gagecock seats.
Gagecocks with ball checks omittedmeet ASME boiler requirements. As analternative method to ASME boilerrequirements, the lower gagecock isavailable with an optional vertical risingball check located in the offset portion ofthe gagecock body, and the uppergagecock has a leaky seat.

The “Arrestor” FugitiveEmission GagecockEnvironmental pollution is a globalissue. Environmental regulationsimpacting plant operations includegagecocks. The “ARRESTOR” OS&Ygagecock is utilized with gage glass,mag gage or other apparatus whenprocess fluid vapors or gases are considered to be environmentally harmful.
Penberthy’s “ARRESTOR” gagecocks areindividually serialized and tested tomeet EPA emission test requirements.Each (550/750 gagecock) is shippedwith its individual test reportthat certifies less than 5 ppm methaneequivalent leak rates using Kalrez®packing. Kalrez®/Zymaxx™, API 607III Edition Fire Test qualified, is apacking material option.
Models 551/751 are available withtype-accepted packing, rated to leakrates of 500 ppm methane equivalent.
Optional materials of construction canbe specified for the gagecock body andtrim. (Trim consists of the stem, stempacking retainer, ball and seat.)Reference Penberthy MaterialSpecification sheets for optionalmaterials.

An internal heating or cooling tube isoffered for tubular and flat glass gages. Thetube passes through the inside of the gageand is in direct contact with the liquid.
Double-and single-sided external heatingand cooling chambers are offered for L andM series gages. External chambers do notcontact the liquid inside the gage.
Lightweight, flexible, silicon-impregnated,fiberglass insulation is available for a widevariety of gagecocks, gages and other instrumentation. Reduces heat or cold lossat temperatures from -65ºF to +1000ºF{-55ºC to +540ºC}. Penberthy insulatingcovers can also be used with frost proofextensions and illuminators.

Frost-proof extensions are clear plasticwindows that fit over the visible part of the glass in flat glass gages. In low temperatureapplications, they prevent build-up of frostover the visible part of the gage resistingobstruction of the view of liquid level.
Drain valves, drain cocks and try cocksare used in the drain or vent connection offlat glass liquid level gages.
An extended packing nut is recommendedfor accommodating gagecocks with protectorsand gage scales for tubular gagecocks.
Gage scales are constructed of corrosion-resistant materials.
PENGAGETM Selection software allows for fast, accurate and simple gage/gagecock specification.
Many other accessories are available.See your representatives for details.
