FCI’s MT Series Multipoint Mass Flowmeters are ideal fortoday's most challenging industrial air or gas handling applicationsand continuous emissions monitoring systems (CEMS). Insidelarge combustion or preheater systems, HVAC units, ducts or flue stacks, MT Series multipoint flowmeters measure flow withexceptional precision under variable thermodynamic conditions.They are an excellent choice for measuring mass flow almostanywhere variable conditions limit single-point flowmeter effec-tiveness. Harsh environments, in which temperature, vibration,abrasion and corrosion pose difficulties for other meters, are no problem for the rugged MT Series multipoint flowmeters.Instrument accuracy is available to ± 2% of reading, withrepeatability of ± 0.5%.

drift for superior repeatability.� Averaging filter dampens response to rapid process fluctuations.� RS232C serial ports for communication with field devices.� Choose 4 to 20 mA, 1 to 5 or 0 to 10 Vdc outputs.� Menu-driven control for ease of service.
� Rack mountable with card slots for expansion and option modules.
� Stainless steel flow element construction; electronics enclosure rated NEMA/CSA Type 4.
� Simple maintenance with modular design and inter-changeable components.
MT86 and MT91 Series Multipoint Flowmeters The MT86 and MT91 Series flowmeters are installed in thou-sands of applications worldwide. The MT91 Series flowmeter ishighly versatile, with a wide turndown range available (from5:1 to 100:1) and flow sensitivity from 0.25 to 150 SFPS [0.08to 46 NMPS]. With its smart digital flow transmitter and advancedthermal dispersion technology flow-sensing elements, the MT91flowmeter meets federal environmental requirements for CEMSper CFR Title 40, Part 75.
The MT86 and MT91 are multipoint flowmeters with sensorarrays of up to 8 (MT86 unit) or 16 (MT91 unit) independentthermal flow sensors with a variable insertion length attached toa junction box and connected via cable to a remote electronicsassembly. Individual flow sensors are placed along a supportassembly to meet application-specific requirements. The flowelement assembly for both the MT86 and MT91 flowmeters isavailable with flanged, threaded or retractable process connectionswith a NEMA /CSA Type 4 junction box or optional explosion-proofflow element enlosure.
Dual sensing point flow element assembly with rack mount MT91 transmitter
The transmitter package for both the MT86 and MT91flowmeters also is housed in a NEMA/CSA Type 4 or optionalexplosionproof enclosure. The MT86 flowmeter's electronicspackage is connected remotely by cable to the flow elementassembly up to 500 ft [152 m] away, while the MT91 flowmeter'selectronics package is similarly connected up to 1000 ft [305 m]away. The MT91 flowmeter's electronics package is also availablein an optional 19-inch DIN or ANSI /EIA rack mount assembly.
Thermal Flow Sensing Element FCI's advanced flowsensing element design, based on thermal dispersion technology,measures air or gas mass flow with exceptional accuracy andrepeatability over a wide range of temperatures and environmentalconditions. Each all-metal flow element features a fouling immuneno-moving-parts design for simple maintenance and long life.The flow element incorporates two platinum resistance-temper-ature detectors (RTDs) for temperature and flow measurement.All wetted surfaces are 316 stainless steel with nickel brazedjoints per AMS 4777 (standard) or Hastelloy C-276 as an option.Coating materials, such as electroless nickel plating or chromiumcarbide are also available.
Mass flow rate is determined by the MT Series multipointflowmeter in the process stream by heating one of its RTDswhile the other senses the temperature of the flowing media.The temperature differential between the RTDs relates to the
mass flow rate and properties of the process media. Higherflow rates or denser media, for example, cause increased cooling of the heated RTD and a reduction in the temperaturedifferential.
Smart Flow Transmitter The MT91 flow transmitterfeatures a powerful microprocessor-driven design for superiorsignal processing and data collection. The design includes a

user-friendly menu-driven structure with LCD screen and keypadfor programming the control, monitoring, display, and driver/alarm functions. A nonvolatile EEPROM chip stores applicationand calibration data, and protects this data in the event of apower disturbance.
RS232C and HART communication ports offer easy linkswith controllers or other field devices. Signal outputs availableare 4 to 20 mA, 1 to 5 or 0 to 10 Vdc. Other features includereal-time temperature compensation, dynamic process temper-ature indication, built-in testing and self-diagnostics, dynamicconversion, display of application statistics and security safe-guards against unauthorized access or tampering.

� Induced or forced draft fan monitoring � Preheater air to boilers or furnaces � Heavy-duty industrial HVAC
Multipoint Versus Single-point Sensing The unstableair currents and gases, often with particulates, that are found inlarge industrial facility ducts or flue stacks and in air or gas han-dling systems turn the task of mass flow measurement into a complexprocess. This task is often beyond the capabilities of single-pointflowmeters or differential pressure averaging devices.
As depicted in the accompanying illustration below, inaccurateflow rate readings can result when single-point metering instrumentsare used in ducts and stacks where large cross-sectional areas orlimited straight-run lengths create irregular flow profiles.
Designed especially for such air/gas handling systems, the MTSeries offers up to 16 sensing points which meter the mass flowrate of individual segments of the flow stream. Representing thoserates, the signal outputs of each sensor element are summed bythe instrument’s control logic to provide an accurate reading oftotal mass flow rate through the entire duct.

Improving the Efficiency of Industrial Air/Gas Systemswith the MT Series Multipoint Mass Flowmeters1. Combustion Air and Preheater AirTo keep boilers, furnaces, and cogeneration units operating at maxi-mum efficiency, individual combustion and preheater air flow feedlines are metered with the MT Series.2. Stack EmissionsReliable and accurate measurement of flow from effluent stacksin power, cogeneration, chemical, paper, refinery, and otherindustrial plants is critical to properly calculate total emissions.The MT Series can be used alone or in conjunction with envi-ronmental and/or radiation monitors for this purpose.3. Flue Gas/Scrubber BalancingIndustrial pollution control systems can be operated far moreeffectively by utilizing the MT Series to meter and balance the flowof flue gas through scrubbers, precipitators and bag houses. Ultra-sensitive, the MT Series offers unsurpassed accuracy across broadflow ranges. The unit’s low-profile, no-moving-parts design causesvirtually no pressure drop in large lines, and the optional abra-sion-resistant probe coating provides outstanding protectionagainst fly ash and other particulate matter.
4. Heating, Ventilation & Air ConditioningUltra-low flow sensitivity, wide turndown and easy duct mountingmake the MT Series the choice for HVAC flow metering. Accurate atthe low flow rates typical in such systems, the MT Series not onlymeasures and totals air flow, it can also be used for controllinglouvers to balance flow within the system.
