NOW – FLT93 Seriesis SIL-2

Compliant

The FLT®93 Series with FlexSwitch® TechnologyFCI’s FLT93 Series Switches with FlexSwitch technology representthe first true technological advance in flow, level, and temperaturesensing and switching in over a decade. A single instrument, easilyfield-configured or factory preset, provides unparalleled accuracy,flexibility, and stability for most flow, level, and temperature sensingand switching needs.

Standardization This sensing and switching breakthrough isachieved in the FLT93 Series Switches by combining a new, highlyaccurate, all-welded sensing element with an advanced, user-friendlyFlexSwitch control circuit.Sensing Element. Two standard sensing element configurations areavailable to meet your most demanding application requirements.The FLT93-S is designed for use in standard heavy industrial applica-tions and in applications with high velocity liquid setpoint require-ments; the FLT93-F is designed for fast response gas applications.Both sensing elements can be supplied in either standard (-40°to +350°F [-40° to +177°C]) or medium (-100° to +500˚F [-73° to+260°C]) temperature configurations. The FLT93-S is also available ina high temperature (-100° to +850°F [-73° to +454°C]) configuration.Control Circuit. One standardized, field-configurable FlexSwitch

Sensing Element Feature Highlights� No moving parts� All welded design� Exotic materials

FLT93-S�Designed for heavy industrialenvironments

�High liquid flow rate sensitivity�High temperature service� Retractable packing glands

FLT93-F� Faster response� Small process connection

Control Circuit Feature Highlights� Temperature compensation� Analog output voltage for flow and temperature� Calibration mode switch to simulate alarm setpoint� Fail-safe setup� Dual alarm, each with SPDT relay/ DPDT optional� Field selected input power

Rack or Socket Mounted Control Circuit Electronics

control circuit satisfies virtually any combination of applicationrequirements. The FlexSwitch technology can be packaged to meetmost integral, remote, and rack mounted configurations.

Precise Performance Accuracy Leveraged from FCI’s field-proven thermal dispersion experience, the unique sensor technologyof the FLT93 Series Switches, combined with FlexSwitch tempera-ture compensation circuitry, introduces unparalleled performancecapabilities:� Exclusive flow accuracy as precise as ±2% of the setpointvelocity over a ±50°F [±28°C] temperature range;repeatability of ±0.5% reading.� Level resolution of ±0.1 inch [±0.5 cm]; repeatability of±0.05 inch [±0.3 cm].� Standard temperature accuracy ±2.0°F [±1°C]; repeatability±1.0˚F [±0.6˚C]. Improved temperature accuracy is availablewith factory calibration.

Integrated Technologies–Advanced FlexSwitch CircuitryAvailable in both standard socket mount or optional rack mountconfigurations, FCI’s fail-safe, dual alarm (SPDT) control circuitprovides the FLT93 Series Switches with unmatched field flexibilityand user-friendliness. The FlexSwitch control circuit also providesthe exclusive advantage of one switch that offers the following field-selectable features:� Dual, independent SPDT relays for the following alarmcombinations:– Flow rate and temperature– High flow and low flow– Point level and temperature– Flow rate and low liquid level– Three-phase level interface– Fail-safe flow, level, or temperature

�One DPDT relay for single alarm of flow rate, liquid level ortemperature is optionally selectable

Application FlexibilityEasy Field or Factory Preset Configurations. FlexSwitch circuitfeatures are easily enabled and can be selected either in-situ orfactory preset. Selections include the following:

FLT93-F and FLT93-S Sensing Elements

FLT93-S and FLT93-F Insertion FlexSwitch

Accuracy and Temperature Compensation FLT93 Seriesswitches are “precision temperature compensated” to insurethe accuracy of factory and field set alarms when installedin dynamic process applications. Accuracy combined withtemperature compensation results in:

� Preventing false alarms or alarm failure� Maximizing operator and process safety� Having the option to set alarms within a narrow set point range

The “Temperature Compensated Flow Curves” graph (right)illustrates how “temperature compensated” flow switches willnot experience signal drift during temperature changes. Whereasa “non-temperature compensated” flow switch experiences signaldrift (as indicated by the red arrow) causing alarm failure.

Typical Monitoring Applications� High/ low pump flow� Relief valve and flare gas flow or leakage detection� HVAC flow monitoring� Monitoring heat exchanger and filter fouling� Drain line flow detection� Pump seal leak and lubricant detection� Wet /dry and sump seal detection� High/ low level alarm and control� Interface control in separation vessels� High and low temperature alarm

Test and Calibration Laboratory Fluid ComponentsInternational maintains an extensive, instrument test and calibrationlaboratory at its headquarters in San Marcos, California. Utilizingthe latest in advanced, computerized data acquisition systems andcalibration test equipment, this facility permits comprehensive prod-uct development, testing, and calibration. Any FCI product can becalibrated in accordance with customer specifications. Laboratorystandards are maintained with NIST (National Institute of Standardsand Technology) traceable Cavitating Venturis (CVs) and preciselycalibrated, pressure and temperature corrected turbine flowmeters.

Combustible and non-combustible gas calibration flow standsallow for the calibration of FCI products in a wide range of gasesand gas mixtures in flow stand line sizes as small as 1/8 inch to30 inches [3 to 760 mm] in diameter. A variety of flow profiles

from laminar to turbulent conditions are generated to duplicateactual field conditions. Flow rates from 0 to 20,000+ SCFM [0 to34,000 NCMH], velocities from 0 to 800 SFPS [0 to 240 NMPS],pressures from vacuum to 3000 psig [200 bar(g)], and tempera-tures from -100º to +900ºF [-70º to +480ºC] are available.

On-Site Calibration and Training In-situ calibration is avail-able from FCI’s Field Service engineers where precise test andcalibration is accomplished in actual media conditions.

FCI’s Training Department can provide on-site or at the factoryProduct Knowledge Workshops for our customers. The work-shops cover installation, setup, and troubleshooting skills, andinclude hands-on exercises using real products, under actualoperating conditions.
