INTRODUCTIONThe Model 3095 MV™ Multivariable™ Mass FlowTransmitter provides cost-effective mass flowmeasurements for steam, gas, or liquids. Thiscompact device accurately measures differentialpressure (DP), static pressure, and processtemperature to dynamically calculate fullycompensated mass flow.

Where traditional meters measure a single processvariable, the Model 3095 MV simultaneouslymeasures all process variables necessary forcalculating either pressure and temperaturecompensated gas flow or temperature compensatedliquid flow. The transmitter then provides a 4–20mA signal proportional to mass flow for control ormetering purposes.

The Model 3095 MV also provides an ideal solutionto replace existing uncompensated volumetric DPflow measurement to pressure and temperaturecompensated mass flow. This permits cost-effectiveplant optimization without changing existing piping,delivering real time information to perform massand heat balances across process units or even yourentire plant.

The pressure and temperature variables are alsoavailable for monitoring or other controllingpurposes without additional penetrations intothe pipe.

GREATER FLEXIBILITYThe Model 3095 MV provides advanced flexibility foryour process measurement needs. All head metersare not the same, therefore the Model 3095 MVflexible design permits the use of several differentprimary elements and tap configurations. The Model3095 MV also provides flexibility by providingdensity and viscosity calculations for a wide range ofprocess fluids. This flexibility allows Model 3095 MVinstallation in multiple plant applications, therebyreducing inventory and spare part requirements.

The Model 3095 MV provides two different steamcalculation options: DP and pressure-compensatedfor saturated steam, and DP, pressure, andtemperature-compensated for saturated andsuperheated steam.

Customer SavingsThe Model 3095 MV providesdramatic savings in installationlabor and hardware costs:

• Single transmitter

• Reduced process penetrationsand hardware

• Single mounting hardware andsingle run of twisted pair

• Less engineering, installation,and commissioning labor

• No DCS (distributed controlsystem) processing time for flowcalculation

• No DCS memory for storage offlow algorithm

• Lower Inventory

ENHANCED FUNCTIONALITYThe Model 3095 MV enhanced functionality givesyou a greater degree of control over your plantoperations, as well as competitive advantages andeconomic benefits. With one device instead of three,installation is easier and maintenance costs arelower. Also, because you have reduced thepenetrations in your process line, you are better ableto meet stringent environmental regulations.

The Model 3095 MV also incorporates the openprotocol HART® (Highway Addressable RemoteTransducer) digital communications format. TheHART protocol provides simultaneous digitalcommunications with the 4–20 mA output.

The Model 3095 MV supports a wide variety of fluidtypes and provides flow computer functionality in asingle, compact package. It does this byincorporating the field-proven performance andreliability you have come to expect from RosemountInc. The integration of multivariable measurement,advanced flow calculations, and advancedconfiguration flexibility into one cost-effective,compact package make the Model 3095 MV the idealchoice for mass flow measurement installations.

WHY FULLY COMPENSATED DP FLOW?Traditionally, DP flow has been calculated in aDCS or flow computer using a simplified mass flowequation. In simplified DP mass flow measurements, aconstant is used to represent many of the terms in theflow calculation:

In fact, only the units conversion factor is constant. Theother terms (discharge coefficient, velocity of approachfactor, and gas expansion factor) are functions of theprocess variables. The simplified flow equation cannotcompensate for changes in these terms, resulting inunrecorded errors in the calculated flow rate.

xReynolds Number

Cd

The constant combines units conversion factor,velocity of approach factor, gas expansion factor, anddischarge coefficient

Compensating flow is the process of combining thedynamic fluid condition values with the flow signal tocalculate true flow. The Model 3095 MV uses a fullycompensated equation for mass flow through anydifferential producer:

The Model 3095 MV provides the greatest DP flowaccuracy over the widest operating range by dynamicallycalculating all flow equation coefficients real time,including discharge coefficients, velocity of approachfactor, thermal expansion effects, and density. This fullycompensated flow equation reduces the sources oftraditional DP flow uncertainty, thereby providing a moreaccurate flow calculation.

MODEL 3095 MV SOFTWAREThe Model 3095 MV has extensive configurationcapabilities, and is easily configured to measureseveral types of fluids.

The Model 3095 MV fast update andcomputation frequencies contribute to its highoverall flow accuracy. Sensor updates occur ninetimes per second.

Model 3095 MV Engineering AssistantThe Model 3095 MV Engineering Assistant (EA)Software is a PC-based software package that offerscomprehensive configuration of the Model 3095 MVMultivariable Transmitter. The EA providesconfiguration technology for the Model 3095 MV tocalculate most mass flow processes in an easy,intuitive manner. It also includes a built-in physicalproperty database.

The EA serves as the primary communicationsinterface to the Model 3095 MV and performsconfiguration, maintenance, and diagnostic functions.

Although the HART Communicator providestraditional smart transmitter functions such asdiagnostics, sensor trim, and analog calibration, theEA is required to configure the Model 3095 MV forflow configurations.

Primary ElementsThe Model 3095 MV supports numerous DP primaryelements for dynamic calculation of dischargecoefficients and gas expansion factors. The EAallows over 25 different primary elements, including:Model 1195 Integral Orifice, Diamond II+ Annubar®,ISO/ASME Orifice Flange Taps, AGA Flange Taps,ISO/ASME corner taps, ISO/ASME Venturi, ISO/ASME Venturi Nozzle, calibrated primary elements,V-Cone®, and Area Averaging Meter.

FIGURE 1. Flow Setup Screen.

Built-in Physical Properties DatabaseIncluded in the Engineering Assistant is anextensive physical properties database allowingdynamic calculation of density or compressibility,viscosity, and related fluid data for over 110 fluids.This data is based on information published byAmerican Institute of Chemical Engineers (AIChE).The complete list of fluids supported by the EAdatabase is listed in Table 1. If desired, a plantengineer can also enter their own fluid (see Figure 1).

Steam – ASMEThe Model 3095 MV dynamically calculates steamdensity for superheated and saturated steam overthe entire operating range. Steam densities arecalculated in accordance with ASME steam tables.For saturated steam applications, the Model 3095MV can also be configured for density calculationsbased on static pressure only (no RTD input).

Natural Gas – A.G.A.The Model 3095 MV calculates natural gascompressibility using either gross or detail naturalgas characterization methods. The flow calculationsare performed according to 1992 A.G.A. (AmericanGas Association) Report No. 3, with A.G.A. ReportNo. 8 for the compressibility factor.

Configuration and SecurityThe Model 3095 MV includes two types of security toprevent unauthorized or accidental changes to theconfiguration. Mounted on the electronics board is asecurity jumper which, when enabled, preventschanges to transmitter configuration. In addition,the Engineering Assistant provides two levels ofoptional password security.

Saves Time—Saves MoneyThe EA saves both time and money because of itsintuitive design (see Figure 1 through Figure 4).Engineering time is saved because the plantengineer does not need to calculate viscosities,densities, flow equations, and related mass flowcalculations. Market research estimates that userscan expect to save four to six hours of engineeringtime per flow application with the EA.

One of the dynamic capabilities of the EA is thecompressibility and viscosity table shown in Figure3. After identifying the liquid or gas and enteringthe operating temperature and pressure ranges,

this table is automatically populated with acomplete set of fluid data over the specifiedtemperature/pressure range.

Another feature is the speed of configuration.With the powerful EA features, a plant engineer canget a process up and running quickly. Later, afterhands-on experience with the process, an engineercan easily modify the Model 3095 MV configurationsand densities to improve product quality and toreduce the formation of by-products.

Intelligent Field DevicesThe Model 3095 MV moves the intelligence of acontrol system away from the DCS out to the fielddevice. By measuring three process variables andcalculating mass flow, the Model 3095 MV frees DCSmemory storage previously used for flow calculationprocessing time and storage of flow algorithms.

The transmitter software allows fieldcommunication via the industry standard HARTprotocol. The HART protocol uses the Bell 202Frequency Shift Keying (FSK) technique. Remotecommunication is accomplished by superimposinga high-frequency signal on top of the 4–20 mAoutput signal.

PROVEN TECHNOLOGYThe Model 3095 MV benefits from the provencapacitance cell technology featured in our Model3051C Differential Pressure Transmitter and thepatented piezoresistive silicon sensor of theModel 3051C Absolute Pressure Transmitter. Thedigital technology employed in the Model 3095 MVensures maximum accuracy and rangeability andremote data communications capability.

The extensive use of application-specific integratedcircuits (ASICs) and surface-mount electronictechnology significantly reduces the size and weightof the transmitter. This Multivariable Transmitteractually performs the same measurement andcomputing functions of other electronic flow measure-ment devices over 10 times its size and weight.

Figure 5 shows a functional block diagram of theModel 3095 MV Multivariable Transmitter. Itsfunctionality is divided between the sensor moduleand the electronics module. The sensor moduleperforms all tasks related to measuring andcorrecting the process variables, while theelectronics module performs the flow calculation,data logging, and output functions.

The Multivariable Sensor ModuleThe advanced Model 3095 MV sensor modulemeasures three process variables simultaneously.The multivariable module incorporates a high-accuracy capacitance sensor for differentialpressure, a high-accuracy piezoresistive sensorfor static pressure, and a four-wire RTD input forprocess temperature measurement. In addition,the sensor electronics convert the process variablesdirectly into digital format for further correctionand compensation within the sensor module.

Differential PressureIn the differential pressure sensor, process pressureis transmitted through the isolating diaphragm andfill fluid to the sensing diaphragm in the center ofthe capacitance cell. Capacitor plates on both sidesof the sensing diaphragm detect its position. Thedifferential capacitance between the sensingdiaphragm and the capacitor plates is directlyproportional to process pressure.

Absolute PressureThe absolute pressure sensor is manufactured witha method called chemical vapor deposition (CVD).This technique, which is superior to othertechnologies that are vulnerable to drift over time,isolates the sensing element from the siliconsubstrate to achieve high accuracyand repeatability.

The absolute sensor consists of a Wheatstone bridgecircuit made from polysilicon resistors deposited ona silicon substrate. The absolute pressure sensor ishydraulically connected to the high pressure side ofthe transmitter. Process pressure is transmittedthrough the fill fluid to the sensing element,creating a very small deflection of the siliconsubstrate. The resulting strain on the substratechanges the bridge resistance in proportion to thepressure applied.

Gage PressureThe gage pressure sensor is manufactured using thesame manufacturing techniques and sensortechnology as the absolute pressure sensor. However,the reference side of the silicon substrate is ventedto atmosphere instead of concealed in the vacuum.

Process TemperatureProcess temperature is measured using an inputconnection on the sensor module for a standardresistance temperature device (RTD). RosemountInc. offers a variety of shielded cables with forconnecting the RTD input to the Model 3095 MV (seeordering information for details).

The Model 3095 MV can accept a signal from any100-ohm alpha 385 platinum RTD that conforms toIEC-751 Class B. The Model 3095 MV MultivariableTransmitter can be supplied with an optionaltemperature sensor. For further information onRosemount temperature sensors and accessoryhardware, contact your Rosemount Representative.

Digital CompensationThe Model 3095 MV uses a dedicated micro-processor, located inside the sensor module,to linearize and correct the raw sensor outputs.To ensure premium performance, this sensormicroprocessor uses the static pressuremeasurement to compensate for zero line pressureeffects and an internal temperature measurementto compensate for thermal effects.

Now Multivariable technology combined with the processflow Engineered Measurement Solution available in theModel 3095 MV improve further on this worldwidestandard of flow measurement.

By providing dynamic calculation of discharge coefficient,gas expansion factor, thermal expansion effects, density,and viscosity as functions of process flow rate, linepressure, and temperature, the Model 3095 MV producesan accurate flow measurement over a broader range ofapplications. Usable flow rangeabilities are furtherexpanded, and performance for given flow rates isimproved. A mass signal is provided, AND the criticalvariables of process temperature and pressure areavailable for monitoring or control purposes withoutadditional penetrations into the process.

A NEW ERA FOR DP FLOWDP flow has the largest installed base of any process flowtechnology. DP meters continue to be purchased more thantwice as often as the next largest flow measurementtechnology, and industry experts expect this trend tocontinue over the next five years (Find/SVP study).

While newer flow measurement technologies have emergedwhich have strengths in certain applications, the DPflowmeter remains a favorite for process flow applications fora number of reasons.

• Excellent repeatability• Proven reliability and stability with proper installation

and application• Direct process mounting• Devices easy to calibrate and troubleshoot• Worldwide industry standard (theoretical and empirical

data readily available)• Installed cost largely independent of line size• One instrument provides a measurement solution

for a variety of applicationsDP flow remains so popular, industry experts predictworldwide purchases of DP flowmeters will exceed half abillion dollars per year over the next five years(Find/SVP study).

Technology has continued to improve the DP flowmeter overthe years. The industry first moved from pneumatic to solidstate analog electronic instrumentation.
