SECTION1 – GENERAL INFORMATION
1 – GENERAL INFORMATION
1.1 – DESCRIPTION
The ELECTRA-flo ThermalAir Flow Transmitter is used in conjunction with ELECTRA-flo Probe(s). One Transmitter
canreceive up to32 individual flowsensors measuring a single ducted airflow orfan.
TheTransmitter'smicroprocessoraveragesflowandtemperaturesignalsfromallsensorsandoutputsananalogsignal
and local display of these averages. The Transmitter serves as the interface for all configuration and diagnostic
functions.
1.2 – THEORY OF OPERATION
The ELECTRA-flo utilizes thermal dispersion
technology to measure airflow. As air moves across
the surface of an elevated temperature sensor, heat is
transferred from the sensor to the airflow in a
mathematically defined relationship between heat
transfer rate and airflow velocity.
Each ELECTRA-flo sensing node utilizes a pair of
precision matched thermistors. One functions as a
reference sensor measuring the ambient air
temperatureat the sensing nodelocation, and the other
thermistoris heated toa preset temperaturedifferential
(∆T)above the ambientairtemperature.Airflowvelocity
is determined using the measured ambient air
temperature, the known heat transfer characteristics
of the heated thermistor, and the power consumed to
maintain the ∆T between the two thermistors.
Using a combination of Computational Fluid
Dynamics (CFD) modeling and extensive full-scale
wind tunnel verification, the aerodynamically
optimized cross section of the sensing node aperture
prevents error inducing turbulence typical of sharp
edged sensing tubes. The aperture’s injection molded shape has been
engineered to minimize the angular flow effects
naturally present in any duct. The flared aperture
captures a representative sample of the ducted airflow,
while the contoured leading edges prevent the creation
of vortices. The center cross section of the aperture
functions in the same manner as a venturi. It stabilizes
and flattens the velocity profile at the point of
measurement ensuring the airflow maintains full
contact with the sensing thermistors. The flow
conditioning characteristic of the aperture
compensates for turbulent airflow with pitch and/or yaw
angles up to ±30 degrees and produces an accuracy
of ±2% of reading for each ELECTRA-flo sensor.

3.1 – OPERATOR MENU
Themicroprocessor program contains aOperator menu systemforselecting parameters. Four
pushbuttons , , , and allow the operator access to the menu for setting configuration modes
andvalues. Refer to the ConfigurationProgramming (Section 5.6) instructionsfor operation details.
Also contained in the Operator menu is an output calibration feature. The calibration method is completely digital
and contains no analog potentiometer adjustments which are susceptible to drift. Non-volatile memory is used for
storingall setup parametersand calibration values, and willremain unchanged afterset, even whenpower to theunit
isoff.
3.2 – DATA DISPLAY
The ELECTRA-flo Thermal Air Flow Transmitter utilizes a high visibility backlit graphical LCD. 3/4" x 2-1/2" display
with three lines of process data, selectable for U.S. or S.I. units. Also used for configuration interface.
3.3 – LARGE OPERATION RANGE
TheELECTRA-flo ThermalAir Flow System can maintain accurate and linear output of flows from 0 to 5,000 FPM.
3.4 – ENCLOSURE
TheELECTRA-floThermalAirFlow Transmitter is housed in an aluminumNEMA 1 enclosure with hinged front cover
for access to power and signal terminals for field connection.

4.1 – RECEIVING AND INSPECTION
•Carefullyremove the ELECTRA-floProbe(s) or Station,andTransmitter from the shippingcontainerand inspect for
any damage. If any damage has occurred in transit, contact freight carrier.
•Reviewthe Factory Set-Up InformationSheetprovided separately and verifythe W.O. # andSerial# match those on
theELECTRA-flo. Verify that the configuration recorded on the Factory Set-Up Information Sheet is correct for your
application. Ifnot,contactAir Monitor'sCustomer Service Department at1-800-AIRFLOW for furtherguidance.
Note:TheELECTRA-flo has been configured to customer provided parameters (see"Factory Setup
InformationSheet" provided separately), and requiresno field calibration/verification prior toinstallation.

Ifadditional protection isrequired, mount theTransmitter in an enclosure with adequate NEMArating.
•Theambient temperature ofthe selected mounting locationmust be between-20ºF to 140ºF. Consideration should
be given to units exposed to direct sunlight.
•Theselected mounting locationshould be rigidand free ofvibration.

Power wiring is done at terminal strip P8, and signal wiring is done at terminal strip P7. Both P7 and P8 are located in
thelowerportionof the unit and areaccessiblebyopeningthefrontcover. SeeFigure4.2 for location ofP7andP8. Two
conduitopeningsare provided for the powerandsignalwiring.
Figure4.2
WIRING. Itis recommended that powerwiring be 14 awgto 18 awg, andsignal wiring should be14 awg to 22awg. 14
awg is the maximum wire gauge that the terminals can accommodate. No more than two wires should be connected
toanyoneterminal. Toaidinthewiringofbothpowerandsignal wires, P7 and P8 are removable by pulling the terminal
strip straight up and off the circuit board. Once wiring has been completed, replace the terminal strip by aligning with
receptacleandpressing firmly.
POWER 24 VAC/DC (Terminals L and N, P8). Power required by the ELECTRA-flo must be connected to the two
terminals labeled L(+) and N(–). Earth ground should be connected to the terminal labeled G. Power Supply must be
20-28VACor20-40VDC.
OUTPUT #1 (Terminals 1 and 2, P7). This output represents the measured airflow and is sourced (powered) by the
ELECTRA-flo. Output can be configured for 0-5VDC, 0-10VDC, or 4-20mADC. Review Factory Set-Up Information
Sheetforyour configuration.
If output is to be 0-5VDC: Position both jumpers on J3. See Figure 4.2.
If output is to be 0-10VDC: Position both jumpers on J2. See Figure 4.2.
If output is to be 4-20mADC: Position both jumpers on J4. See Figure 4.2.
