SECTION 1 - INTRODUCTION
The AVT3000 product family is intended for applications that require accurate and repeatable
airflow measurement with high turn-down with precise closed-loop control using an external PI
controller. The AVT3000 incorporates a state-of-the-art vortex shedding digital transmitter
with an intuitive user-interface software known as the AccuValve Insight.
Theory of Operation (Reference the Diagram Below)
The AccuValve®divides the airflow into two equal chambers using an airfoil shaped
compression section. Each chamber is comprised of a vortex shedding airflow sensor, a
modulating control surface and a static regain section. As air enters the chambers it accelerates
and compresses, creating an ideal location for measuring airflow velocity. The vortex shedding
airflow sensors provide a highly repeatable digital pulse-train with a frequency that is directly
proportional to the air flow velocity in each chamber of the AccuValve®.
The digital pulses generated by each vortex shedding sensor are used to calculate the total
airflow volume flowing through the AccuValve®. The transmitter provides a software-
selectable analog output signal that is directly proportional to the total airflow volume
measurement. The airflow volume can also be provided directly to the building management
system’s BACnet MS/TP network by ordering the optional BACnet MS/TP communications
module.

SECTION 4 - INSTALLATION
Read all instructions and review the installation diagrams provided on the following pages prior
to beginning installation. Also reference the product submittal drawings before proceeding.
WARNING: Wear eye protection, cut-resistant gloves, and clothing suitable for working
with sheet metal. Failure to do so may result in personal injury.
1. Verify the tag number located on the valve label matches the HVAC schedule.
2. Locate the duct section which the valve is servicing and select a suitable mounting
location for the valve.
NOTE: the AccuValve does not require straight-run inlet conditions to operate properly,
however it’s always best to follow HVAC Best Practices for Commercial Buildings during
installation which includes locating the valve away from transitions and bends to
minimize impact on system static pressure. Also, be sure to select a location that will
provide a minimum clearance of 14” (356mm) unobstructed access to the transmitter,
actuator and valve access cover.
3. Provide an opening in the duct section sized appropriately for the valve being installed.
NOTE: A slip-fit valve will require an opening approximately 2” smaller than the valve
length and a flanged valve will require an opening the same as the valve length. For
valve dimensions, reference Section 4.
4. Install duct hangers within 12” (305mm) from each end of the valve connections.
Reference Section 4 for valve weights.
WARNING:Use duct hangers and hardware designed to support the total load of the
valve and associated duct sections. Failure to do so may result in serious personal injury
or death.
5. Install the valve into the duct in accordance with the airflow direction label located on
the valve. Position the valve for easy access to the control module side. Since the
AccuValve is not position sensitive, it can be installed in any plane or rotational axis
without having impact on the performance.
NOTE: Screws, nuts, fasteners, duct sealant, hangers, companion flanges and gaskets
are NOT provided by Accutrol.

Power Source Switch
The AVT3000 Transmitter pcb has a Power Source Switch which should always be in the
“Operational Position” for the transmitter to function normally. The “Nonoperational
Position” is provided so the transmitter can be programmed or configured when there is no
24v power source available. This is a convenient feature for configuring the BACnet
parameters or the transmitter’s analog output prior to having the 24v power source wired.
Operational Position
Nonoperational Position
24v power is provided to the transmitter
through the 24v connector. This is the
normal position for the Power Source
Switch.
5vdc power is provided to the
transmitter through the computer
connected to the USB Configuration Port.
This is a temporary position only.
Caution:The Power Source Switch must be returned to the Operational Position after
completing the configuration otherwise the transmitter will not function.

6.6.2 Airflow Volume Gauge
The Airflow Volume Gauge provides the real-time measurement of the volumetric air flowing
through the AccuValve. The range of this gauge is determined by the size of the valve and it
cannot be reset in the field.
6.6.5 Valve Airflow Gauge
The Valve Airflow Volume Gauge provides the real-time measurement of the volumetric air
flowing through the AccuValve. The range of this gauge can be configured to match the full-
scale range of the Analog Output or it can be configured with a full-scale range that is
independent of the Analog Output. To change the full-scale range, click on the gauge face.
6.6.5 AccuNet Totalizer Gauge (Only available when the AccuNet Board is Installed)
The AccuNet Gauge displays the sum of the airflows reported by all the devices connected to
the AccuNet network. This gauge can only be activated by configuring this device as the
Totalizer on the local AccuNet network. The full-scale range of this gauge can be configured to
match the full-scale range of the Analog Output or it can be configured with a full-scale range
that is independent of the Analog Output. To change the full-scale range, click on the gauge
face.
