Optional ScreensMicro-Orifices ® must be used with extremelyclean fluids (filtered to .03 microns).Otherwise, there is a high probabilityof clogging the orifice with solid particles.Even with clean fluids, there is alsothe possibility of introducing contaminantsduring assembly of the fluid system. Tominimize the possibility of clogging smallorifices, it is recommended that screens beinstalled on the upstream and downstreamsides of the orifice, to protect against handlingcontamination.Fifteen micron screens are normally usedwith Micro-Orifices ® , to minimize contaminationthat occurs during handling orassembly. Screen material is stainless steel.Ordering InformationIdentify the part number of Micro-Orifices ®using the complete detail on the chart atright.

34Fundamentals of Flow MeasurementGAS FLOW MEASUREMENTThe Standard Cubic FootVolumetric FlowThe flow of gases is traditionally measuredin volumetric units such as cubic feet, litersor cubic centimeters. However, sincegases are compressible fluids, the totalmass contained in a given volume varieswith both the temperature and pressure ofthe gas. To provide a meaningful referencefor volumetric flow measurements, a"standard" set of conditions are defined fortemperature and pressure of the gas.Unfortunately, the definition of standardconditions varies slightly in technicaldisciplines and industry groups. Standardtemperature ranges from 32 to 70ºF (0 to20ºC). Standard pressure is generallyaverage atmospheric pressure at sea-level,14.7 psia.Standard ConditionsFor the data presented in the charts onpages 16-18, standard conditions are 70°Fand 14.7 psia. For data points measuredby O'Keefe Controls Co., the same standardconditions are used.A mass flowmeter measures flow accurately andrelatively independent of barometric pressure.The unit shown above is used to obtain the data forcalibrated orifices.Factors to ConsiderIn comparing volumetric flow measurementstaken at different locations andwith different measuring equipment,the following factors should be considered:• Definition of Standard ConditionsBetween 32ºF and 70ºF, the standardconditions can vary up to 8%.• Temperature of the GasA 10ºF deviation causes about 1%error in a rotameter reading. Moreor less deviation occurs in other typeflow measuring instruments. The deviationsare predictable and the flowmeasurement is correctable.• Barometric PressureNormal atmospheric pressure variationsof ±1/2" Hg. can cause morethan 1% error in rotameters. Altitudeis also an important factor, since thebarometric pressure decreases rapidlywith increasing altitude. At anelevation of 2,000 ft. above sea level,rotameter scale readings are in errorby 3-1/2%. These errors can be correctedquite easily with predictablecorrection factors, and accurateknowledge of barometric pressure.What To Do To ImproveMeasurement AccuracyIn many applications, errors of ±10% inflow rate are unimportant. In this case,corrections for 1) standard conditions, 2)barometric pressure and 3) temperatureare not required.1. Definition of Standard ConditionsThe data on pages 16-18 is for standardconditions of 70ºF and 14.7 psia. To reconciledata taken from volumetric instrumentswhich are referenced to differentstandard conditions, use the followingformula:Q s= Q mx P m x T SP ST mQ m= measured volumetric flow (SCFH)or (SLPM).Q s= volumetric flow corrected to 70ºFand 14.7 psia.P m= standard barometric pressure referencedby manufacturer (psia). This is generally14.7 psia.P s= standard barometric pressure = 14.7 psia.T m= Standard absolute temperature referencedby manufacturer (ºRankine).T s= standard absolute temperature = 530ºR.For Example:A mass flowmeter manufacturer uses thefollowing standard conditions:14.7 psia, 32°F (492°R)To convert to standard conditions of 70ºF(530ºR) and 14.7 psia, apply the following:Q S= Q mx P mx T S= Q mx 14.7 x 53014.7 492P S= 1.077 Q mT mThe volumetric flow Q Sis larger than Q mby 7.7%.

Temperature EffectsAir FlowThe flow of gases through an orifice variesinversely as the absolute temperature.As the gas temperature rises and the gasdensity decreases, the mass flow rate alsodecreases.To extend the chart data on pages 16, 17for air flow, use the following formula.QT T= Q S ST TWhere:T S = standard absolute temperature °R(°R = 460 + °F).T T = non standard absolute temperature °R.Q S = flow from chart at 70°F = 530°R.Q T = flow at a different temperature.EXAMPLE:At 70°F and an inlet pressure of 25 psigthe No. 60 (.060" dia.) orifice has a flowrate of 55 SLPM (see page 17).

The basic formula forwater flow isQ = C v ∆PQ = flow in GPM∆P = pressure differential in psiC v = flow factorFor a flow of 1 gpm at ∆P = 1, the C v = 1To obtain the water flow rate through precisionorifices use the above equation and obtainthe C v value from the charts on pages16, 17, 18.EXAMPLE:Size Number 100 (.100" dia.) has a C v = .23For a 25 psig pressure differential:Q = C v ∆ P = .23 25 = 1.15 GPMB. Other LiquidsFor liquids other than water, the equationbecomes:∆ PQ = Cv S.GWhere:S.G. = Specific gravity of the liquid(The specific gravity of water is 1.0)To obtain the flow rate of an oil with S.G. =.85, use the above equation and obtain theC v value from the charts on pages 16, 17, 18.EXAMPLE: Size number 100 (.100" dia.)has a C v = .23For a 25 psig pressure differential:Q = C v∆ P = .23S.G.25 = 1.25 GPM.85Specific Gravity of VariousLiquids Relative to Water @ 60ºFAlcohol, Ethyl .79Gasoline .75Glycerine 1.26Kerosene .80Diesel Oil .85Lube Oil .90Turpentine .87Water 1.00Test ProceduresA. Rotameters - Gas FlowRotameters for measurement of air or othergas flows must be used for the conditionsfor which they are calibrated. Typically theyare calibrated for the following:• Air Flow• Outlet Conditions - 14.7 psig @ 70ºFRotameters can be calibrated for other gasflows or other outlet pressure conditions.Manufacturers also provide graphs or tablesfor correction of measured data when conditionsvary from the calibration conditions.When using rotameters calibrated for standardoutlet conditions use the test proceduresshown below.Positive Supply PressureAirInSupplyPressureVacuum SourceAtmosphericInletPressureRotameterOrificeOrificeRotameterExhaustToAtmosphereVacuumGageToVacuumSourceB. Mass Flowmeters - Gas FlowMass flowmeters are generally insensitiveto gas pressure or barometric pressure conditions.Consequently their location in thetest circuit is not critical. Consult your instrumentmanufacturer for recommendedtest procedures.C. Instrument Accuracy - Gas FlowThe three variables to be measured in gasflow applications are:• Pressure• Temperature• Flow RateThe accuracy of the flow measurement of agas through an orifice is limited by the combinedaccuracy of the instruments used inthe measurement. Expected accuracy of agas flow measurement is generally in therange of 1 to 20%. 1% accuracy can only beachieved with high quality instruments.P.O.

Calibrated OrificesWATER OR AIR FLOW37Air FlowFor flow standards or other critical uses,O'Keefe Controls Co. can provide measuredair flow data for any of the standard precisionorifice products. This optional serviceis available at a nominal charge and can beprovided for pressure or vacuum flow conditionsin the standard ranges listed below.A calibration sheet with measured data isprovided for each orifice (see sample below).Data is obtained using a digital mass flowmetertraceable to the National Institute ofStandards Technology (NIST). Standardconditions are 70ºF and 14.7 psia(See photo page 34).Air flow can be measured for any of thefollowing conditions:Pressure 0-5, 0-10, 0-20, 0-50, 0-100 psigVacuum 0-30" HgFlow 0-.002, 0-.01, 0-.02, 0-.05,0-.1, 0-.2, 0-.5, 0-1, 0-2, 0-5,0-10, 0-20, 0-50, 0-200 SLPMFlow 0-.004, 0-.02, 0-.04, 0-.10,0-.2, 0-.4, 0-1, 0-2, 0-4, 0-10,0-20, 0-40, 0-100, 0-400 SCFHC v MeasurementWater at a constant height equivalent to 1 psig isused to determine the amount of water that passesthrough a test orifice in a measured time period.The C v is calculated from the measured data.Water FlowCalibration of standard orifices using waterflow is accomplished by measuring thequantity of water flowing through an orificein a given time period at a specific inletpressure.The calibration procedure determines thewater flow rate through the orifice and thecorresponding C v of the orifice is calculated.The C v can then be used to predictthe water flow rate at varying differentialpressure conditions using the equation:Q = C v∆PFor liquids other than water flow rate canalso be predicted using the C v method. Seepage 36 for details on liquid flow - C vmethod.A calibration sheet with measured data isprovided for each orifice.

38The Basic ConceptA greatly misunderstood and misappliednotion is that of “choked flow”, also referredto as “critical flow”.In gas flow through an orifice there is an occasionwhere the gas velocity reaches sonicconditions. This occurs for air flow when theabsolute pressure ratio is .528, i.e. when thedownstream absolute pressure (P 2) is 52.8%of the upstream absolute pressure (P 1).P 1P 2Sonic velocity occurs for air flow whenP 2 /P 1 ≤ .528.AirVelocity➔The air flow velocity is limited once the absolutepressure ratio is ≤ .528.For air flow through an orifice with aninlet air temperature of 68 o F the choked(sonic) velocity is 1129 ft/sec.The Misconception!Once sonic velocity is achieved in orifice airflow (P 2/P 1= .528), it is easy to "assume" thatthe mass flow rate is constant for all pressureratios less than .528; i.e. P 2/P 1≤ .528. Forexample, when P 2is 14.7 psia and P 1is 27.84psia, sonic velocity occurs through the orifice.As P 1further increases there is no furtherincrease in the velocity of the air flowingthrough the orifice.P 1 = 27.84 psia= 13.14 psigSonic VelocityConditions for the onset of sonic velocity in orifice air flow.Consider all the Factors!The mass flow rate through an orifice is a functionof three basic parameters.Q (flow) is a function of• Velocity• Density• Orifice Area1129 ft/sec @68°FAir velocity isconstant inthis region01 .528➔ 0P 2 /P 1 – Absolute Pressure RatioSonic VelocityThrough OrificeP 2 = 14.7 psia= 0 psigChoked Flow of GasesWhen the air velocity reaches sonic velocity(P 2/P 1≤ .528) further increases in P 1(upstreampressure) do not cause any further increase inthe air velocity through the orifice. Consequentlyit is wrongly concluded that the massflow rate also does not increase.As the air pressure (P 1) increases, the densityof the air also increases; and since the massflow rate is also a function of density, the massflow rate increases linearly with pressure (P 1).MassFlow Rate➔Sonic VelocityAir Velocity01 .528Mass FlowRateP 2 = 14.7 psia= 0 psigEven though the air velocity through the orifice is limitedto the speed of sound, the mass flow rate continues toincrease as the absolute pressure (P 1) increases.What is Choked?The parameter that becomes “choked” or“limited” is the velocity of the air. It is moreaccurate to use the term “choked velocity”rather than “choked flow” when the absolutepressure ratio of air through an orifice is≤ .528.Vacuum ConditionsP 1 = 14.7 psia= 0 psigStandardAtmosphericConditionsAir at atmospheric pressure enters the orifice and flowsto a downstream vacuum pump.In the case of vacuum conditions on the outletof an orifice and where the inlet is at ambientatmospheric pressure, both the air velocityand the mass flow rate become choked(limited) when sonic velocity is achievedthrough the orifice.➔MassFlow RateTUTORIALFor atmospheric inlet pressure and downstream vacuum,both the air velocity and mass flow rate are limited.The reason for the mass flow rate limitation isthe fixed inlet density combined with the fixedvelocity. The flow charts on pages 16-18 showthe choked mass flow effect for vacuum conditions.At vacuum levels between 15-30” Hgthe mass flow rate is fixed.Choked Flow for PositivePressure ConditionsAs in the case of the above vacuum conditionsthere are certain situations in which chokedflow does occur for positive (above atmospheric)pressure. By maintaining a fixed inletpressure to the orifice and allowing theoutlet pressure (back pressure) to vary, thereis a range of outlet pressures over which themass flow rate is fixed.For example (see chart below).• With an inlet pressure of 80 psig, the massflow rate is choked (limited) for all outletpressures less than 35.30 psig (includingvacuum conditions).• The actual flow rate is constant for theoutlet pressure range of 35.30 psig to aslow as a complete vacuum. The flow ratecan be obtained from the charts on pages16-18; e.g. for an orifice of .010" diameterand with 80 psig inlet pressure, thechoked flow rate is 8.4 scfh (page 16). Thisflow rate will be constant for all outletpressure conditions between 35.30 psigand full vacuum.P.O.

AIR PROXIMITYSENSORGENERAL DESCRIPTIONThe air proximity sensor is a non-contact,no-moving-part sensor, capable of detectingthe presence of an object at ranges up to1/8". In the absence of an object, air flowsfreely from the sensor resulting in a nearzero output signal. The presence of an objectwithin the sensing range deflects thenormal air flow and results in a positiveoutput signal.At low supply pressure, flow from thesensor exerts only minute force on the objectbeing sensed and is consequently appropriatefor use where the object is lightweight,or easily marred by mechanical sensors.Since there are no moving mechanicalparts in the air proximity sensor, there are noinherent wear mechanisms or life limitations.In this regard, the sensor is not cycledependent and is particularly appropriatefor applications requiring large numbers ofcycles. Also, the air proximity sensor isinherently explosion-proof and self-purging.Consequently, it is suitable for many adverseenvironments.OUTPUT PRESSURE – Po - In H 2 O765432100P s 1 PSIGP s 3/4 PSIGP s 1/2 PSIGP s 1/4 PSIGSPECIFICATIONSSupply Pressure: Up to 10 psig.Supply Flow: 0.5 scfm @ 1 psig2.3 scfm @ 10 psigOutput Signal Pressure: See Output Pressurevs. Range Curves.

Air Proximity SensorPrinciple of OperationOUTPUTSIGNALOFFIn the absence of an object disturbing the free flow of air exiting from the sensor,the output pressure signal is in an "off" condition. This "off" condition is a nearzero output pressure.PROXIMITY SENSORP/N OKC 818 (Formerly 6080517)5/64 OD OUTPUT CONNECTIONFOR 1/16" ID SOFT TUBINGNORMAL FLOWOUTPUTSIGNALONWhen an object is located inside the sensing range, the sensor flow is deflectedwith a resultant pressure buildup in the output. This pressure signal is the "on"condition of the sensor. The amount of pressure sensed increases as the objectmoves closer to the sensor.

Low Dew Point Air Dryers3SELF-REGENERATIVEDescriptionThe air dryer products of O'Keefe Controls Co. employ a selfregenerative,desiccant style drying system. "Self-regenerative"means that the dryer automatically and continuously dischargescollected water vapor which has been removed from the air passingthrough the system. Desiccant style means that a material(a desiccant) is used to selectively remove water vapor from the airsurrounding this material. Three common desiccant materials aresilica gel, alumina and molecular sieve.How It Works!In the O'Keefe Controls Co. air dryers desiccant material is amolecular sieve. This type desiccant absorbs the water vapormolecule in tiny pores on the surface of each bead of the molecularsieve material. Moist air passing by this desiccant is dried as vapormolecules are selectively attracted to the pores in the molecularsieve beads. A dew point as low as minus 100°F is possible usingmolecular sieve material.Another equally important characteristic of the molecular sieve isthat extremely dry air (very low dew point) passing by thisdesiccant will reabsorb the water vapor trapped in the pores; thusproviding a means of automatic regeneration of the desiccant.Two desiccant tanks are employed in each air dryer. Wet pressurizedair enters one tank and is dried as it passes through to the outlet.A portion of the dried air is directed into the top of the second tankthrough a purge orifice and flows at near atmospheric pressurethrough this tank to atmosphere. As this dry air passes around themolecular sieve beads it reabsorbs water vapor and then exhauststo atmosphere.Flow Patterns in Desiccant Air DryerThe flow patterns shown below have a repeating cycle period of 60seconds. For 30 seconds the left tank is pressurized; for 30 secondsthe right tank is pressurized.Dew Point and Relative HumidityDew Point – Temperature at which condensation begins. Air is fullysaturated with water vapor at this temperature.Atmospheric Dew Point – Dew point when air is at atmosphericpressure.Pressure Dew Point – Dew point when air is at elevated pressureabove atmospheric pressure.Relative Humidity – Ratio of the actual water vapor content to thesaturated water vapor content.See chart below.Weight of Water In a Cubic Foot ofAir at Various TemperaturesWeights shown in grains 7,000 grains = 1 lb.Temp Relative Humidity Temp.°C 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% °F-6.7 .124 .247 .370 .494 .618 .741 .864 .988 1.11 1.24 204.4 .285 .570 .855 1.14 1.42 1.71 1.99 2.28 2.56 2.85 4015.6 .575 1.15 1.72 2.30 2.87 3.45 4.02 4.60 5.17 5.75 6026.7 1.09 2.19 3.28 4.37 5.47 6.56 7.65 8.75 9.84 10.93 80Construction of Desiccant TankMain Flow OutMain Flow InLoad SpringSupport ScreenFine ScreenFilter MediaMolecularSieve BeadsFilter MediaFine ScreenSupport ScreenThe desiccant tank constructionis vital to reliable operationof the air dryer.

Point-of-Use Air Dryer System17DEW POINT REDUCTIONDescriptionThe "point-of-use" compressed air dryer removesliquid water using filters; and reducesthe pressure dew point of the air throughpressure reduction. The system consists of aprefilter and a coalescing filter, followed bya pressure regulator. Two gages and mountinghardware are included in the system.Maximum flow rates of 10, 20 and 40 scfmare available as standard.While depression of dew point with thesystem is not as dramatic as in desiccant airdryers, it is an economical approach to solvinglocal in-plant air line water problems.How It Works!Assume that the air entering the filters containsliquid water and water vapor at 100%relative humidity. The air exiting the filtersis virtually free of liquid water, but is still at100% relative humidity as it enters the pressureregulator.Since pressure regulators reduce pressure,there is a corresponding decrease in thedensity of the air at the exit from the regulator.Not only is the density of the air reduced,but also that of the water vapor, resulting ina decrease of the relative humidity. Saturatedwater vapor entering the regulator is nolonger saturated in the reduced pressure atthe outlet.The dew point chart (at right) illustrates thereduction of dew point that can be achieved.The lower the outlet pressure of the regulatorthe lower is the relative humidity and associateddew point. The assumption for the chartdata is that heat transfer maintains the temperaturereasonably constant during flowpassage through the pressure regulator.Where To Use the Air Dryer!Install this dryer close to the "point of use" toinsure that there is no substantial temperaturedecrease between the regulator anddownstream use point.It is good practice to maintain the regulatoroutput pressure a minimum of 20 psi belowthe regulator input pressure. The two gagesprovided are for this purpose.Point-of-use air dryer contains two filters,two pressure gages and one regulator.Ordering InformationPart Maximum ConnectionsNumber Flow – SCFM NPTOKC-2039-1 10 scfm 1/4"OKC-2039-2 20 scfm 3/8"OKC-2039-3 40 scfm 1/2"DimensionsCPrefilterInletNPT1/8" NPT -Male (2)(2) MountingBracketsFilters remove condensate before airenters regulator.

Pneumatic Controls23SENSORSPneumatic Pressure SwitchThe Pneumatic Pressure Switch combines apressure sensing element and a spool valve toproduce a switching device with an adjustableset point. The assembly is non-electric, usingonly air or inert gas in the switch unit.The pressure sensor is compatible with air,water, steam, oil and many corrosive liquids orgases. Setpoint is adjustable – vacuum up to 6000 psig.Air signals from the 5 ported 4-way valve in the switch unit can beeither vacuum or positive pressure up to 100 psig. RequestBulletin OK-043.Pneumatic Liquid Level SwitchThe Liquid Level Switch is an air sensor fordetecting liquid level inside a vessel. The floatmechanism mounted within the vessel operatesa ceramic coated magnet. A magneticallyactuated sensor on the outside of the solidmetal housing reacts to the inner magnet movement.The movement shifts a 3-way air valve.Both side mounted (shown here) and top mountedunits are available. Wetted materials are brass or stainless steel.The magnetic sensor unit operates at air pressure from 30 to 100psig. The 3-way valve signals can pilot alarms or control elements.Request Bulletin OK-242.Pneumatic Flow SwitchThe Pneumatic Flow Switch is an air sensorfor detecting the flow of liquids or gases ina pipe. A paddle extends into the fluid and deflectsas the stream velocity increases or decreases.Various sized paddles establish the particularfluid stream flow rate at which the external magneticsensor is actuated.The air sensor is a 3-way valve which operates atpressures from 30 to 100 psig. Flow switch units are available from1/2" to 2" NPT. Wetted materials are brass or stainless steel.Request Bulletin OK-268.Air Jet Proximity SensorThe Air Jet Proximity Sensor is a non-contactno-moving-part sensor, capable of detectingthe presence of an object at rangesup to 1/8". In the absence of an object,air flows freely from the sensor resultingin a near zero output signal. The presence of an object within thesensing range deflects the normal air flow and results in a positiveoutput signal.Air supply pressure is 0.5 to 10 psig. Output signals are lowpressure and sufficient to actuate air/electric switches or air/airamplifiers. Request Brochure OK-098.Pneumatic Temperature SwitchThe Pneumatic Temperature Switch combines atemperature sensing element and a spool valve toproduce a switching device with an adjustable setpoint. The assembly is non-electric, using only air orinert gas in the switch unit.The temperature sensor is available in direct mount(shown here) or with a bulb and capillary. Wettedmaterials are copper or stainless steel.Air signals from the 5 ported 4-way valve in theswitch unit can be either vacuum or positive pressure up to100 psig. Request Bulletin OK-088.Pneumatic Liquid Level IndicatorThe Liquid Level Indicator displays the heightof liquid above the tip of an air tube immersedin the liquid. A small amount of airbubbles through the liquid of a vented vessel.The back pressure in the sense tube isdisplayed on a gage. This back pressurecorresponds to the height of the liquid above the top of the sense tube.Ranges of liquid height vary from 0-1 in. to 0-60 ft. RequestBulletin OK-267.Differential Pressure Flow SwitchThe Differential Pressure Flow Switch uses a calibratedflow element to provide pressure signals to anadjustable setpoint differential pressure electricswitch. Gases or liquids can be used. Wettedmaterials are aluminum, brass or stainless steel.Adjustable flow rate setpoints are available forwater flow ranges from 15-50 sccm to4-12 GPM. Request Bulletin OK-269.Magnetic Proximity SensorThe Magnetic Proximity Sensor detectsthe presence of a magnetic or steel part inits near vicinity. The 3-way normally closedair valve is actuated when in the presenceof a small magnet or steel part. The valvedeactuates when the small magnet or steelpart is removed.Since magnetic fields penetrate materials such asaluminum or stainless steel, the proximity sensor readily detects aproperly polarized magnetic piston in a cylinder constructed withaluminum or stainless steel barrels. It is often used in place of limitswitches to detect end of stroke position.The sensor is available with mounting straps for attachment to around cylinder barrel. Request Brochure OK-248.P.O.
