SMV 3000 Sensor and Flow Transmitter Functions

Honeywell’s SMV 3000 SmartMultivariable Flow Transmitterextends our proven “smart”technology to the measurementof three separate processvariables simultaneously with theability to calculate compensatedmass or volume flow rate as afourth process variable accordingto industry standard methods forair, gases, steam and liquids. Itmeasures differential pressureand absolute or gauge pressurefrom a single sensor andtemperature from a standard 100-ohm Resistance TemperatureDetector (RTD) or thermocoupletype E, J, K, or T input signals.The SMV 3000’s flow calculationmay include compensation ofpressure and/or temperature aswell as more complex variablessuch as viscosity, dischargecoefficient, thermal expansionfactor, velocity of approach factorand gas expansion factor.

Proven Pressure SensorTechnology withcharacterizationThe SMV 3000 utilizes provenPiezoresistive sensor technologyand has an ion-implanted siliconchip hermetically sealed in itsmeter body. This singlepiezoresistive capsule actuallycontains three sensors in one; adifferential pressure sensor, anabsolute or gauge pressuresensor, and a meter bodytemperature sensor. Processpressure applied to thetransmitter’s diaphragm transfersthrough the fill fluid to the sensor.Voltage bridge circuits on the chipmeasures the differential andstatic pressures while a resistor ina voltage divider measures thetemperature. These three inputsignals from the sensor coupledwith the characterization datastored in the transmitter EPROMare then used by themicroprocessor to calculate

highly accurate pressure andtemperature compensated valuesfor the differential pressure andstatic pressure measurements.In this way, the SMV 3000 canprovide an output signal that isstable and fully compensated forchanges in process pressure andambient temperature over a verywide range. Microprocessor-based electronics coupled withthe sensor characterizationprovide higher span-turndownratio, improved temperature andpressure compensation, andimproved accuracy.

Process TemperatureMeasurement andCompensationSimilar to the differential andstatic pressure measurements,the SMV 3000’s temperatureelectronics are characterized forambient temperature changes sothat the resistance or millivoltinput from a Pt. 100 Ohm RTD orType J, K, T or E Thermocoupleis compensated for ambienttemperature effects and thereforecan be reported as the mostaccurate temperature possible.The SMV 3000’s flexibility allowsthe connection of either astandard 2, 3 or 4 wire 100 ohmRTD or a Type J, K, T or Ethermocouple without specialinstallation consideration. RTDs,thermocouples and thermowellscan be ordered from Honeywellunder this specification. Seepages 22 and 23.

Mass Flow Measurements forSteam, Air, Gas or LiquidThe SMV 3000 includes flowequations for steam, air, gas andliquids so that one model is allyou need in your plant. Themass flow equation with dynamiccompensation (Equation 1) isbased on the ASME MFC-3M-1989 standard for orifice meters.

Equation 1:

Qm = NCEvY1d2 h w ρ f

Where,Qm = mass flowrateN = units conversion factorC = discharge coefficientY1 - gas expansion factorEv = velocity of approach factorρf = density at flowing conditionshw = differential pressured = bore diameter

SMV 3000 Flow CompensationMost differential pressuretransmitters utilized in steam, gasand liquid flow applications todaymeasure the differential pressureacross a primary flow elementand report it to a DCS, PLC orflow computer for flow calculation.Most often, the calculation insideassumes that the density of thefluid is constant per the followingequation.

Qv = K h

ρWhere,

Qv = volumetric flowratehw = differential pressureK = flow factorρ = flowing density

In other applications, one will takethe equation a step further andcompensate for changes inpressure and temperature usingadditional pressure andtemperature transmitters. Forexample, if a gas is beingmeasured, the following volumetricflow equation based on multipletransmitters - the “Old” approach -applies (Figure 2). Or, in the caseof Mass flowrate,

The “Old” Flow ApproachFlow Computer or DCS

On the other hand, if you have amore demanding flow applicationutilizing an orifice plate or laminarflow element that requires highaccuracy at larger flowturndowns, choose the morecomplex mass or volumetric flowequation and compensate fordensity as well as other variablessuch as viscosity, dischargecoefficient, gas expansion factor,velocity of approach factor andthermal expansion factor.

Description of FlowVariables for Dynamic Flow

Compensation

Figure 2 — Flow Compensation Using the “Old” Approach Discharge CoefficientDischarge coefficient is defined as

Today, the three keymeasurements (differentialpressure, static pressure andprocess temperature) and the flowcalculation can be made with onemultivariable transmitter. So,whether you just want tocompensate for density or use fulldynamic flow compensation,consider the SMV 3000 and the“Enhanced” flow approach (Figure3). Unlike most DP transmitters,the SMV 3000 with dynamiccompensation can correct flowerrors due to the K factor. Per

With the SMV 3000, you have theflexibility to choose which variablesyou need to compensate. Forexample, the transmitter can beeasily configured to compensate fordensity only and calculate flowratevia a standard equation. If you havea liquid, steam or gas applicationwith small flow turndownrequirements, choose the easy,standard equation and in minutesyour mass or volumetric flowrate iscompensated for density changes.

the true flowrate divided by thetheoretical flowrate and correctsthe theoretical equation for theinfluence of velocity profile(Reynolds number), theassumption of no energy lossbetween taps, and pressure taplocation. It is dependent on theprimary flow element, the β ratioand the Reynolds number.Reynolds number is in turndependent on the viscosity,density and velocity of the fluid aswell as the pipe diameter per thefollowing equation: (next page ⇒ )

Equation 1, the K factor is not aconstant and can vary:

k = NCEvY1d2

Dynamic flow compensation is theprocess of measuring the requiredvariables (differential pressure,static pressure and temperature)and using these variables toperform real time, calculations ofvariables such as density,viscosity, Reynolds number,discharge coefficient, thermalexpansion factor and gasexpansion factor - all which caneffect the accuracy of your massflow measurement.

Where,ν = velocityD = inside pipe diameterρ = fluid densityµ = fluid viscosity

The SMV 3000 can be configuredto dynamically compensate fordischarge coefficient.

This method follows the standardStoltz equation for orifice, Venturiand nozzle primary elements topredict discharge coefficient forflowrate in the turbulent regime -Re > 4000.

b = function of primary elementRe = Reynolds numbern = depends on the primary

Dynamically compensating fordischarge coefficient allows theSMV 3000 to obtain better flowaccuracy at higher turndowns fororifice, Venturi and nozzles.

Thermal Expansion FactorThe material of the process pipeand primary flow element expandsor contracts with changes intemperature of the fluid beingmeasured. When a primary flowelement, such as an orifice, issized, the flowrate is calculatedbased on the Beta ratio (d/D) at 68degrees F. The SMV 3000, usingthe thermal expansion coefficientswhich are dependent of thematerial of the pipe and flowelement, calculates the change inBeta ratio per the followingequations:

β = d/DD = 1 + αp(Tf - 68)Dref

d = 1 + αpe(Tf - 68)dref

Where,β = beta ratioD = pipe diameterd = bore diameterDref = pipe diameter at design

temperaturedref = bore diameter at design

temperatureαp = Thermal Expansion Coef.

of pipeαpe = Thermal Expansion Coef.

of boreTf = flowing temperature

As an example, a fluid at 600degrees F could cause as muchas 1% error in flow measurementusing 300 series stainless steelmaterials.

Gas Expansion FactorThe gas expansion factor correctsfor density differences betweenpressure taps due to expansion ofcompressible fluids. It does notapply for liquids which areessentially non-compressible andapproaches unity when there aresmall differential pressures for gasand steam measurements. Thegas expansion factor is dependenton the Beta ratio, the Isentropicexponent, the differential pressureand the static pressure of the fluidper the following equation:

Y1 = 1 - (0.41 + 0.35β4)X1/k

Where,β = beta ratioX1 = hw /Pk = isentropic exp. (ratio of

specific heats)

The SMV 3000 dynamicallycompensates for gas expansioneffects and provides better massflow accuracy, especially for lowstatic pressure applications.

Velocity of Approach FactorEv is dependent on the Beta ratio asdefined by the following equation:

Ev = 1/ 1- 4Β

In turn, Beta ratio is dependent onthe bore diameter and pipediameter which are functions oftemperature. The SMV 3000compensates dynamically forvelocity of approach factor bycalculating the true Beta ratio atflowing temperature. This ensureshigh flowrate accuracy at low andhigh temperature applications.

Density and Viscosity of FluidsDensity directly effects the flowratecalculation as well as the dischargecoefficient due to changes in theReynolds number. The SMV 3000can be configured to compensatefor density of fluids due to changesin the temperature and/or pressureper the following:• Gases as a function of P and T

per the Gas Law Equations.• Steam as function of P and T

based on the ASME Tables.• Liquids as a function of T per a

5th Order Polynomial.

ρ = d1 + d2TF + d3TF2 + d4TF

3 + d5TF4

Changes in the viscosity of a fluiddue to changes in temperature canalso effect the Reynolds numberand therefore discharge coefficient.The SMV 3000 can compensatethe viscosity of liquids based on thefollowing 5th order polynomialequation:

µ = v1 + v2TF + v3TF2 + v4TF

3 + v5TF4

Support of Proprietary Flow Elements

The SMV 3000 with dynamic flowcompensation supports orificemeters and the Meriam LaminarFlow Elements. The SMV 3000with density compensation supportsother flow elements such asVenturi meters, nozzles, averagingpitot tubes.

Averaging Pitot TubesAveraging pitot tubes are a lowdifferential pressure, insertion typeflow element and can be used inclean steam, air, gas and liquidapplications. Since averaging pitottubes are insertion type elements,they have lower installation coststhan many other primary flowelements. The SMV 3000 can beconfigured to compensate fordensity and calculate flowrate forliquids, gases and steam utilizingaveraging pitot tubes (Figure 4).

Meriam Laminar Flow ElementLaminar Flow Elements (Figure 5)are gas volume rate of flowdifferential producers operating oncapillary flow principles and aresimilar to averaging pitot tubes inthat they are low differentialpressure producers. They areapplicable over wider flow rangesthan conventional types ofprimary flow elements and areideally suited for measurementsof combustion air and gases suchas argon, helium and nitrogen.Laminar Flow Elements behaveaccording to the following flowformulas and can be configuredfor standard volumetric flowrate:

Qv = (B x hw + C x hw2) • (µs/µw) •

(Ts/Tf) • (Pf/Ps) • (ρw/ρd)

Where,Qv = standard volumetric flowrateB & C = calibration constants

Figure 5 — SMV 3000 with MeriamLaminar Flow Elements

hw = differential pressureµs = standard viscosityTf = flowing temperaturePf = flowing pressureρw = wet air densityρd = dry air density

And for mass flowrate:

Qm = Qv • ρWhere,

Qm = standard volumetric flowrateρ = density at standard conditions

The relationship betweenflowrate and differential pressurecan be determined two ways.The first method uses a 6thorder polynomial equation thatcustom fits the flow element.The second method is an n-segment fit (maximum n = 5)between flow and differentialpressure which also custom fitsthe flow element.

The SMV 3000 can use either oneof these methods as well ascompensate for density andviscosity to increase the accuracyof the flow measurement for theLaminar Flow Element overgreater flow turndowns.

Other Multivariable ApplicationsMost multivariable transmitters areused in flow applications.However, there are otherapplications which require thatmultiple process variables (DP, APand T) be transmitted to a controlsystem - DCS or PLC. It is in thecontrol system where a calculationsuch as compensated level forliquid level applications or complexcalculations to infer composition indistillation columns are performed.A SMV 3000 in these applicationscan save substantial wiring,installation and purchase costsversus 2 or 3 separate single-variable transmitters. Whetherintegrating digitally to a TDC/TPS3000 Control System or providing4 analog 1-5 V outputs to a PLC orDCS via the MVA MultivariableAnalog Card, the SMV 3000 isvery cost effective in multivariableapplications.

Smart Configuration FlexibilityLike other Smartline Transmitters,the SMV 3000 features two-waycommunication between theoperator and the transmitter via theSCT 3000 Smart ConfigurationToolkit or SFC - Smart FieldCommunicator. You connect theSFC or SCT anywhere that you canaccess the transmitter signal lines.Communicators provide thecapabilities of transmitteradjustments and diagnostics fromremote locations, such as thecontrol room. The SFC and SCTsupport other Smartline Instrumentstoo: ST 3000, STT 3000 andMagneW Plus.

Smart Field Communicator

The SCT 3000 has an advantageover the SFC in that it can also beused to configure the completeSMV 3000 database and save thisdatabase for later access. TheSCT 3000 is a software packagewhich runs on an IBM compatiblecomputer utilizing the Windows 95,Windows 98 or Windows NTplatforms. The SCT 3000 must beused to configure the advancedflow parameters for the SMV 3000.

savings are achieved, as wellas reduced costs of piping,manifolds, mounting, safetybarriers, etc., with the SMV3000 due to its unique ability

To measure both differentialand static pressure with a singlesensor, and ProcessTemperature with an externalRTD or thermocouple.By dynamically calculating thecompensated mass flow, theSMV 3000 totally eliminatesthe need for a dedicated flowcomputer, or it can free yourcontrol system from performingthis function.

• Commissioning - The hand-held SFC III Smart FieldCommunicator or SCT 3000Smart Configuration Toolkitlets a single technicianremotely configure SMV 3000Smart Multivariable FlowTransmitters and re-rangethem when applicationrequirements change. TheSCT must be used toconfigure the advanced flowparameters.

• Maintenance - The SMV 3000offers greater accuracy andstability, reducing thefrequency of calibration. Self-diagnostics can automaticallyindicate impending problemsbefore they affect reliability oraccuracy. Also, a singletechnician can diagnoseproblems remotely, using theSFC, SCT 3000 or TPS GlobalUser Station, saving time andreducing cost. The SMV3000 also prov ides improvedreliability with a single devicereplacing up to threetransmitters.
