The Series AVLV Low Air Velocity Transmitter quickly and accurately measures air
velocity or volumetric flow in imperial or metric units. Simultaneous current and voltage
outputs on all models provide universal inputs to monitoring equipment while the
output range, units, and 0-5/10 VDC output can be configured via local DIP switches.
The optional integral display, or the portable remote display tool, provide a convenient
way to locally monitor process values and configure the unit.
Models are available in 1% and 2% accuracy models and low velocity ranges to
suit a variety of needs, and the optional BACnet MS/TP or Modbus® RTU/ASCII
communication protocol allows units to be daisy-chained while providing access to all
of the velocity and flow data, as well as additional information such as air temperature.
The lower ranges in these high accuracy units allow for applications in quality intensive
environments, such as the pharmaceutical industry.

Voltage Output Operation
CAUTION
RESULT.
The terminal block is removable, and each of the terminals are labeled underneath the
terminal block on the circuit board. The voltage output and the power supply must have
separate wire leads that are only joined at terminal 2 of the transmitter, as shown in
Figure 2. Additional error may occur for the voltage output if a single wire is used or if
the wires are joined at the power supply or receiver. The connections to the transmitter
are made to terminals 1, 2, and 4 (PWR, GND, and VOUT respectively) on the terminal
block as shown in Figure 4.

Current Output Operation
RESULT.
The terminal block is removable, and each of the terminals are labeled underneath
the terminal block on the circuit board. As the power supply and outputs share the
same common signal (GND), the outputs may have separate wires but must effectively
join at terminal 2 of the transmitter, as shown in Figure 1. The connections to the
transmitter are made to terminals 1, 2, and 3 (PWR, GND, and IOUT respectively) on
the terminal block as shown in Figure 4.

RESULT.
The maximum length of connecting wire between the current transmitter and the
receiver is a function of wire size and receiver resistance. That portion of the total
current loop resistance represented by the resistance of the connecting wires
themselves should not exceed 10% of the receiver resistance. For extremely long
runs (over 1,000 ft.), it is desirable to select receivers with higher resistances in order
to keep the size and cost of the connecting leads as low as possible. In installations
where the connecting run is no more than 100 ft, connecting lead wire as small as No.
22 Ga. can be used.
GND
CAUTION
Shielded two wire cable is recommended for current output loop wiring. Ground the
shield at the power supply end only.
COM
Power Supply
Choose a power supply with a voltage and current rating sufficient to meet the power
specifications under all operating conditions. If the power supply is unregulated, make
sure the output voltage remains within the required voltage range under all power line
conditions. Ripple on the supply should not exceed 100 mV.
For a 24 VDC nominal power supply, this evaluates to RMAX = 1100 ohms.
D0(-)
Electrical Connection:
The Series AVLV is powered and simultaneously transmits a two-wire 4-20 mA current
output and a three-wire 0-5 VDC or 0-10 VDC voltage output via a removable four
conductor terminal block. The transmitter power supply common is used to reference
the current and voltage outputs so either current, voltage, or current and voltage may
be wired according to the application. The range of the voltage output can be selected
using the on board DIP switches as described in the Analog DIP Switch Settings
section of this manual.
RMAX = (VPS – 2.0) / 0.02 where VPS is the power supply voltage
D1(+)
Duct Mount:
The transmitter should be mounted away from fans, corners, heating and cooling
coils, and other equipment that will effect the measurement of the air velocity. It
is recommended that the AVLV is mounted 10 duct diameters downstream of any
disturbances and 5 duct diameters upstream of any disturbances, if possible.
1. Mark and drill a 0.750-0.938˝ (20-24 mm) diameter hole into the duct.
2. Insert and center the duct mount flange in the previously drilled hole and mark
location of the three mounting screw holes.
3. Remove the mounting flange and drill or punch the mounting holes in the marked
locations.
4. Fasten the flange to the duct using three #8 x 1/2 pan head sheet metal screws. Do
not over tighten screws.
5. Insert the AVLV probe into the ducts mount flange and set the desired insertion
depth.
6. Note the flow direction and unit alignment as shown on sensor tip and product label,
tighten probe retention set screw on the duct mount flange screw to affix the probe in
place.
Although low loop resistances are recommended, the absolute maximum current loop
load resistance, RMAX , is defined by the following the equation:
VOUT
INSTALLATION
CURRENT
RECEIVER
POWER
Figure 1: Current output wiring
The minimum receiver load is 1 kΩ. The resistance due to the wire should be low
compared to the receiver load resistance. While the voltage at the terminal block
remains unchanged with a 10 mA current flow, resistive losses in the wiring do cause
errors in the voltage delivered to the receiver. For a 1% accurate gauge, the resistance
of the wires should be less than 0.1% of the value of the receiver load resistance. This
will keep the error caused by the current flow below 0.1%.
The output across VOUT and COM will be either 0-5 VDC, 0-10 VDC, or the inverse
depending on the DIP switch setting. See the Analog DIP Switch Settings section for
more information.

• When the switch is in the ON position, the output directly follows the input (i.e. output
increases as the input increases).
• When the switch is in the OFF position, the output acts in reverse of the input (i.e.
output decreases as the input increases).
CALIBRATION
There is a 5 second delay from the time the zero or span calibration
buttons are released until the time that the change in calibration
takes place. This delay is used to reduce vibration or disturbances of the user related
to the button presses.
NOTICE
The security level that is set in the Programming Menu section
of the manual will determine which calibrations, if any, may be
adjusted by the user.
NOTICE
Zero Calibration
The zero calibration can be set by covering the sensor to ensure no air flow and
pressing the zero button for 3 seconds. If either the remote or local LCD is present, the
display will read ZEro and then sequence back to the home display.

SPAN Calibration
The span calibration can be adjusted only after setting the zero adjustment. It must
be completed within 5 minutes of the last zero calibration. The span calibration button
will be ignored until the zero calibration is completed. Place the sensor in airflow that
matches the maximum selected range of the transmitter. Press and hold the span
button for 3 seconds. If either the remote or local LCD is present, the display will read
SPAn and then sequence back to the home display. If the span calibration is attempted
before adjusting the zero calibration, the FAiL error message will be displayed briefly
before returning to the home display.

Display Error Messages
ovEr = The air velocity is greater than the maximum span value causing an Over
Range Error
UndEr = The air velocity is less than the minimum span value causing an Under Range
Error
FAiL = When the span or zero buttons are pressed, the air velocity value is out of the
range to allow a correct setting. This may be due to a sensor failure.
Err1 = The sensor is damaged.
PROGRAMMING MENUS
Home Menu
During normal operation, the display will be in the Home Menu and will display the
current measured pressure and the engineering units.
Menu Access Security
While in the Home Menu, press and hold the Zero and Span buttons simultaneously
until SECUr appears on the display in order to access the other programming menus.
Upon releasing the buttons, the display will indicate the current security level.
If the current security level is the security level desired (i.e. Security Level 0), press
and hold the span button for 3 seconds to enter the Velocity or Air Flow Menu.
If the security level is not the desired level, the security level can be changed
temporarily to a lower security level or permanently to a higher level of security by
pressing the zero button. A security code will appear on the display, and it can be
changed to one of the codes listed in Table 3. The span button chooses which digit
and the zero button increments the value of that digit. Pressing and holding the span
button will store the value.
The level of access to the programming menus and the calibration is limited based on
the security level. Table 3 details the level of access for each security level.

Mode Selection / Digital Dampening Menu
From the home display, pressing the span and zero button simultaneously for 3
seconds will access the Menu Security Level. If the level is set to 0 or 1, pressing and
holding the span button for 3 seconds, a second time, will access the Mode Selection
Menu. The display will default to air velocity when first powered up. Pressing the zero
button will cycle to air flow.
Once the desired mode is displayed, pressing and holding the span button for 3
seconds will save the selected mode and display the digital dampening or averaging
parameter. This parameter stabilizes the output and the display by averaging the
readings. There are 2.5 readings taken each second and the user can select the
number of seconds that they would like to average, up to 240 seconds. The display
and the output will continue to update at a rate of 2.5 updates per second, but the
moving average is used for these updates.
Velocity Mode
K-Factor Adjustment
If the Velocity Mode was selected, pressing and holding the span after adjusting the
digital dampening will enter the Velocity Mode and the transmitter will display the
engineering unit that has been selected by the DIP switch. Pressing and holding the
span button for 3 seconds will enter the K – Factor adjustment. The K – Factor can
be adjusted between 0.001 to 9.999. The K-Factor can be adjusted by pressing the
span button to select the digit and pressing the zero button to increment the value of
the digit. Pressing and holding the span button for 3 seconds will enter the Maximum
Output Adjustment parameter.
Flow Mode
K-Factor Adjustment
If the Flow Mode was selected, pressing and holding the span after adjusting the digital
dampening will enter the Flow Mode and the transmitter will display the engineering
unit that has been selected by the DIP switch. Pressing and holding the span button for
3 seconds will enter the K–Factor adjustment. The K–Factor can be adjusted between
0.001 to 9.999. The K-Factor can be adjusted by pressing the span button to select
the digit and pressing the zero button to increment the value of the digit. Pressing and
holding the span button for 3 seconds will enter the Area Adjustment parameter.
Area Adjustment
For flow applications, the area is multiplied by the velocity to determine the volumetric
air flow. The area will be listed in either CFM or m3/h depending on the DIP switch
settings. The units will appear on the display at the time of adjustment. The area can
be adjusted by pressing the span button to select the digit and pressing the zero button
to increment the value of the digit. Pressing and holding the span button for 3 seconds
will enter the Maximum Output Adjustment parameter.
Maximum Output Adjustment
The maximum output can be equivalent to air velocity or air flow. After adjusting
the K-Factor, the display will indicate if the adjustment is set for velocity or air flow.
Pressing the zero button will toggle between the selections. Pressing and holding the
span button for 3 seconds will enter the maximum output adjustment. The maximum
output can be adjusted by pressing the span button to select the digit and pressing the
zero button to increment the value of the digit. Pressing and holding the span button
for 3 seconds will save this value and go to the Security Update Menu.
Security Update / Save Changes Menu
The Security Update Menu allows the security level to be set either higher or lower
than the current security level setting. This security level will be displayed the next
time the Menus are accessed from the home screen. Pressing the zero button cycles
through the security levels. Pressing and holding the span button for 3 seconds
accepts the new security level and gives the option to save all the menu changes.
Pressing the zero button will toggle between yes and no. Yes will save the changes
made to all menu items and no will discard all the changes made to all menu items. If
the display is set to yes, pressing and holding the span will save the menu items and
return the display to the home position.
FACTORY DEFAULT PROCEDURE
In order to reset all of the menu settings back to their factory programmed values,
press and hold both the span and zero buttons simultaneously for 10 seconds until
FACt is displayed on the LCD. Upon releasing the buttons, the unit will be factory
defaulted. Since resetting the transmitter will wipe out all changes, it is necessary to
zero (and possibly span) the transmitter before taking measurements.
MAINTENANCE/REPAIR
Upon final installation of the Series AVLV Air Velocity Transmitter, no routine
maintenance is required besides zeroing the transmitter occasionally. Besides routine
calibration and installation of the LCD, the Series AVLV is not field serviceable, and
it is not possible to repair the unit. Field repair should not be attempted and may void
warranty.
