ELECTRA-flo - IO&M Manual
ELECTRA-flo
SECTION 1 – GENERAL INFORMATION
1 – GENERAL INFORMATION
1.1 – DESCRIPTION
The ELECTRA-flo Thermal Air Flow Transmitter is used in conjunction with ELECTRA-flo Probe(s). One Transmitter
can receive up to 32 individual flow sensors measuring a single ducted airflow or fan.
The Transmitter's microprocessor averages flow and temperature signals from all sensors and outputs an analog
signal 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
temperature at the sensing node location, and the
other thermistor is heated to a preset temperature
differential (T) above the ambient air temperature.
Airflow velocity 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.
Air Monitor Corporation
116-053-13.P65 (2/28/12)
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.

SECTION 3 – FEATURES
3 – FEATURES
3.1 – OPERATOR MENU
The microprocessor program contains a Operator menu system for selecting parameters.
Four pushbuttons UP, DN, ENT, and ESC allow the operator access to the menu for setting configuration modes and
values. Refer to the Configuration Programming (Section 5.6) instructions for 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 storing
all setup parameters and calibration values, and will remain unchanged after set, even when power to the unit is off.
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
The ELECTRA-flo Thermal Air Flow System can maintain accurate and linear output of flows from 0 to 5,000 FPM
(Low Range) and 0 to 10,000 FPM (High Range). Consult Factory for Custom Range.
3.4 – ENCLOSURE
The ELECTRA-flo Thermal Air Flow Transmitter is housed in an aluminum NEMA 1 enclosure with hinged front cover
for access to power and signal terminals for field connection.
3.5 – MULTIPLE OPERATING POWER SELECTIONS
The ELECTRA-flo Thermal Air Flow Transmitter can be powered by either 24VAC or 24VDC.

4.1 – RECEIVING AND INSPECTION
• Carefully remove the ELECTRA-flo Probe(s) or Station, and Transmitter from the shipping container and inspect for
any damage. If any damage has occurred in transit, contact freight carrier.
• Review the Factory Set-Up Information Sheet provided separately and verify the W.O. # and Serial # match those
on the ELECTRA-flo. Verify that the configuration recorded on the Factory Set-Up Information Sheet is correct for
your application. If not, contact Air Monitor's Customer Service Department at 1-800-AIRFLOW for further guidance.
Note:
The ELECTRA-flo has been configured to customer provided parameters (see "Factory Setup
Information Sheet" provided separately), and requires no field calibration/verification prior to installation.
4.2 – LOCATION
• The standard version of the ELECTRA-flo Transmitter is a NEMA 1 enclosure suitable for most clean indoor locations.
If additional protection is required, mount the Transmitter in an enclosure with adequate NEMA rating.
• The ambient temperature of the selected mounting location must be between -20ºF to 140ºF. Consideration should
be given to units exposed to direct sunlight.
• The selected mounting location should be rigid and free of vibration.

4.5 – POWER/SIGNAL CONNECTIONS
Power wiring is done at terminal strip P8, and signal wiring is done at terminal strip P7. Both P7 and P8 are located
in the lower portion of the transmitter and are accessible by opening the front cover. See Figure 4.2 for location of P7
and P8. Two conduit openings are provided in the bottom of the transmitter for the power and signal wiring.
Figure 4.2
WIRING. It is recommended that power wiring be 14 awg to 18 awg, and signal wiring should be 14 awg to 22 awg.
14 awg is the maximum wire gauge that the terminals can accommodate. No more than two wires should be
connected to any one terminal. To aid in the wiring of both power and signal 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 receptacle and pressing firmly.
POWER 24 VAC/DC (Terminals L, N and G, P8). Power required by the ELECTRA-flo must be connected to the two
terminals labeled L(+) and N(–). Earth ground must be connected to the terminal labeled G. Power Supply must
be 20-28VAC or 20-40VDC.

4. Connect a DMM set for type and scale of Transmitter Output 1 (as indicated on display) across terminals 1 and
2 on the ELECTRA-flo (see Figure 4.2).
Note: If the output is 4-20mA, a load resistance should be in series with the DMM. This can be accomplished
by connecting the actual process load or a resistor of similar value to the actual process load.
DMM should be reading a minimum value; 0.00 ± 0.01 volts or 4.00 ± 0.01mA.
5. If DMM is reading out of tolerance, use UP or DN to adjust the ELECTRA-flo output for an acceptable DMM
reading.
Depending on DMM's selected range, the UP or DN button may need to be pressed and held for a period of
time before any change occurs in the DMM's display. To speed up changes in output, pushbutton combinations
can be used. The following chart lists these combinations along with the associated change in output type.

PROP_DESCRIPTION
The Air Monitor BACnet stack supports the optional property “PROP_DESCRIPTION”. This is used to
indicate the type of information in the object. For example, for an ELECTRA-flo system, the description will
indicate as “AF0” for average flow, or “AT0” for average temperature. If the object belongs to a sensor in the
system, it will be indicated as “STn” or “SFn”, where n is the sensor address. The Air Monitor Device which
supports BACnet will determine the amount of AI objects available. For an ElectraFLO system, the amount
of AI objects is determined by the total number of sensors in the system x 2 with an additional 2 AI objects
for system average flow and system average temperature. So an ElectraFLO system with 8 sensors will
have a total of 18 AI objects. These are for average Flow and average DP. This object does not support
intrinsic reporting, so the event state is always “NORMAL”.
Usage of the Status Field.
–
Each object supports status bits IN_ALARM, FAULT, and OUT_OF_SERVICE.
–
OVERRIDDEN is not supported as it makes no sense to override a value with no reasonable substitute.
–
The OOS property indicates the physical input to the object is not in service. In the case of an ElectraFLO
system, this will be set by the transmitter if someone intentionally removes the sensor from the network.
If the transmitter determines there is a problem with any sensor in question, the OOS bit is set along
with the FAULT bit. If the OOS property is set, data from the physical device will not be used in any
calculation.
–
IN_ALARM is set for values which exceed the predetermined values set in the transmitter memory.
Sensor analog objects will not typically have this flag set. This will be done at the transmitter level
indicating the average flow or temperature are out of range.
