Thank you for purchasing the Spirax Sarco MTI10 insertion or MTL10 inline Thermal Mass Gas Flowmeter and Temperature Transmitter. The Model MTI10/MTL10 is one of the most technically advanced flowmetersintheworld.TheMTI10/MTL10utilizethesamesensorandelectronics.TheMTL10includesacompanysuppliedflowtube,whilethe MTI10 is inserted into an existing pipe. Extensive engineering effort hasbeeninvestedtodeliveradvancedfeatures,accuracymeasurementperformance and outstanding reliability.

This Instruction Manual contains the electrical and mechanical installationinstructionsaswellasdetailsforprogramming,maintainingand troubleshooting the meter.

Thismanualisdividedintothefollowingsections:Introduction,Installation,Wiring,Operation,CalibrationValidation,Modbus,Maintenance,Troubleshooting,andAppendices. Theory of OperationThe MTI10/MTL10 is an innovative Thermal Mass Gas Flowmeter andTemperatureTransmitter.Itismicroprocessor-basedandfieldprogrammable. The MTI10/MTL10 thermal sensor operates on the law that gases absorb heat. A heated sensor placed in an air or gas stream transfers heat in proportion to the stream’s mass velocity. There are two sensor elements connected to a balanced bridge circuit. One sensor element detects the gas temperature and a second element is maintained at a constant temperature above the gas temperature. The energy applied to the heated sensor to maintain a constant temperature differential(constant∆T)isdirectlyproportionaltothemassflowvelocity.TheMTI10/MTL10flowmetermaintainsaccurateflowmeasurement over a large temperature and pressure range.

Mass FlowTheModelMTI10/MTL10measuresmassflow;anadvantageoverotherflowmeterswhichmeasurevolumetricflowrate.Volumetricflowis incomplete because temperature and pressure are unknown and mustbemeasuredseparately.Forexample,themassflowofagasdepends on its temperature and pressure. As temperature and pressure changes,thegasvolumechangesbutnotitsmass.Thereforeadevicemeasuringmassflowisindependentoftemperatureandpressure.TheModelMTI10/MTL10providesadirectmeasurementofgasflowinMassunits(kg/hr,lb/hr),standardunits(SCFM,SLPM)ornormalunits(NM3/hr,NLPM)withnoadditionaltemperatureorpressuremeasurementsrequired.

Flow Calibration

Calibration ValidationSpirax Sarco has developed a method to validate the calibration of the flowmeterinthefield.ThismethodiscalledCalibrationValidationandit is made up of two distinct tests: CAL-V™ and Zero CAL-CHECK™. The goal of Calibration Validation is to provide operators with the ability to verify that the meter is capturing accurate data at scheduled recalibration times - or at any time - instead of sending the meter back to the factory for recalibration.

ByperformingCAL-V™inthefield,operatorscanverifythatthemeteris running accurately by testing the functionality of the sensor and its associated signal processing circuitry. This test can be done in the pipeandinnormalprocessingconditions.Thesecondtest,ZeroCAL-CHECK™,ensurestheeffectivenessandsensibilityofthesensorata"noflow"condition.

Starting Up CAL-V™CAL-V™ may be performed at any time after installation and at any flowrate,includingzeroflow.Youdonotneedanyextraequipmentorpaperwork to perform a CAL-V™ test. Refer to "Performing a CAL-V™ Calibration Validation Test" on p. 74 of this User's Guide to start CAL-V™.

Starting Up Zero CAL-CHECK™There are a few ways that Zero CAL-CHECK™ is different than CAL-V™:• The Zero CAL-CHECK™ test must be performed at a "no flow"

condition(iezeroflow)• IftheZeroCAL-CHECK™testistobeperformedinthepipe,thefield

baseline must be set before an actual test can be performed (see "Setting Field Baseline for In-Situ Zero CAL-CHECK™ Tests" on p. 67).

• IftheZeroCAL-CHECK™testistobeperformedoutofthepipe,the meter must be set upside-down (probe pointing up) and the PVC sensor protector that the meter was shipped with must be placed back over the sensor to achieve the factory baseline that the meter has been set with.

Techniques for Achieving Zero Flow - In the PipeIn-situ (in the pipe) Zero CAL-CHECK™ testing can be achieved in one of two common ways:1. Packing Gland Assembly

Thefirstin-situoptionisachievedthroughtheuseofthePackingGland Assembly that may be ordered as an option for most inline- or insertion- type meters. The assembly allows the operator to retract and isolate the sensor from the process in order to conduct the Zero CAL-CHECK™test.Thisisparticularlybeneficialforapplicationsinwhich the process is not easily stopped.

2. Pipe Bypass / Valving-OffThesecondin-situoption,ifspaceallows,istoredirecttheflowthrough a bypass pipe section or valve off the meter in order to isolate the meter's sensor in the place where it has been installed. While the flowisredirected,theZeroCAL-CHECK™testcanbeperformed.Oncethetestiscomplete,thevalvestothebypassmaybeclosedandflowmaybedirectedbacktothemeter'ssensorwhereflowmonitoring can continue as normal.

MODBUS

Introduction ScopeThis section describes the MODBUS implementation for the Spirax Sarco MTI10/MTL10 Mass Flow Meter based on the Modicon Modbus Protocol (PI-MBUS-300 Rev. J).

MODBUS is an application layer messaging protocol that provides client/server communications between devices. MODBUS is a request/reply protocolandoffersservicesspecifiedbyfunctioncodes.

ThesizeoftheMODBUSProtocolDataUnitislimitedbythesizeconstraintinheritedfromthefirstMODBUSimplementationonSerialLinenetwork(max.RS485ApplicationDataUnit=256bytes).Therefore,MODBUS PDU for serial line communication = 256 – Server address (1 byte) – CRC (2 bytes) = 253 bytes.

RS-485 ADU = 253 + Server address (1 byte) + CRC (2 bytes) = 256 bytes.

For more information on MODBUS go to the web site http://www.modbus.org/

Command Request:<Meter Address> <Function code> <Register start address high> <Register start address low> <Register count high> <Register count low> <CRC high> <CRC low>

Command Response:<Meter Address> <Function code> <Data byte count> <Data register high> <Data register low>… <Data register high> <Data register low> <CRC high> <CRC low>Note: The data shown in brackets < > represent one byte of data.

MTI10/MTL10 Commands supportedThe MTI10/MTL10 supports the following commands:1. Function 03: Read holding registers.2. Function 04: Read input register.3. Function 06: Preset single register.

Read Holding Registers (command 03)This command reads the basic variables from the MTI10/MTL10 and has the following format:

Troubleshooting: General

Installation ProblemsThe following is a summary listing of problems that may be encountered with the installation of the MTI10/MTL10 Thermal Mass Flowmeter.1. Improper wiring connections for power and/or 4 to 20mA output

signal. The MTI10/MTL10 require a separate power source for the main board and the two 4 to 20mA output signals. Two wires supply 24VDC power to the main board. Two wires are used for each of the 4 to 20mA output signals. Refer to Figure 3.4 (p. 19) and Figure 3.5 (p. 20). Also refer to "Wiring Precautions" and "Helpful Hints" in Wiring section (p. 15) for further guidance.

2. Inadequate power source. Forthosemodelsthatarepoweredby24VDC,a24VDC±10%,0.75 amp or greater power supply is recommended. If the voltage supplied is not within this range or if the power supply is not rated for25wattsminimum,avarietyofproblemscanoccurincludinginaccurateflowreadings,dimdisplayandfaultyprogrammingaction.The input voltage must be within the range of 23 to 25VDC as measuredatthepowerinputterminalsoftheflowmeterelectronics.

3. Flow measurement seems inaccurate.• ChecktoensurethattheflowmeterisinstalledsothattheFlow

MTI10/MTL10 2 Gas CurvesThe 2 Gas Curves firmware allows the use of two different calibration tables when running with different gases. One of two methods can be used to switch between the two calibration curves:

1) Use of Contact Input:Whenthecontactinputisprogrammedforcurveswitching,anopencontact will select curve #1 and a contact closure will select curve #2.

2) Use of the Keypad:Ifthecontactinputisnotprogrammedforcurveswitching,pressingF2 and F3 simultaneously will prompt an operator to manually switch curve upon entering a password and confirming the action by pressing the appropriate key.

PressingF2&F3simultaneously:
