Installation & Operation Manual - Model AVT4000

SECTION 1 - INTRODUCTION
The AVT4000 product family is intended for applications that require accurate and repeatable
airflow measurement with high turn-down that achieves precise control using an external PI
controller. The AVT4000 incorporates a state-of-the-art vortex shedding digital transmitter
with an intuitive user-interface software known as the AccuValve Insight.
1.1 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.
Field configuration is accomplished through AccuValve Insight, which is an intuitive user-
interface software. Connection between the AVT and the computer is provided through a USB
port located on the AVT transmitter or using the optional Bluetooth connection.

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.
CAUTION: 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 3 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 transmitter 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.

valve into the duct engaging
valve into duct 1” at each end.
1. Slip the inlet end of valve into the duct far
enough to allow the valve to be lifted into the

3. Position valve to provide
unobstructed access to the
control module, actuator and

1. Slip the companion flanges over each end of the duct and install to duct as required.
5. For clean air applications,
apply UL181 compliant foil tape
over the valve/duct seams.
For corrosive exhaust applications, apply PTFE tape (available from Accutrol)
over the valve/duct seams.

1. Verify the opening in the duct is properly sized for the valve and installation method being used. Also verify
both ends of the duct where the valve is to be attached are true and square before attempting to install valve.
If the duct ends are not square and true, do not attempt to install valve as it will not operate properly.
2. Lift valve into position to provide
unobstructed access to the control
module, actuator and access panel.
3. Install gaskets and/or duct

NOTE: It’s acceptable to fabricate and install flanges onto the AccuValve and ductwork on location. If
flanges are fabricated on site, it’s still important to verify both ends of duct are true and square prior to
and after installing flanges, otherwise the valve will not operate properly.

viewing the real-time performance of the AVT4000 valve. The Dashboard provides an intuitive
graphical user interface that is easy to understand while providing easy access to the field-
configurable parameters. The diagram below shows the AVT4000 Dashboard followed by brief
descriptions of each on the following pages.

6.5.2 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.
6.5.3 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.

6.5.4 Analog Output Configuration
The AVT’s Analog Output is primarily used to provide an analog signal representing the Airflow
Volume flowing through the valve. The signal type and full-scale range of the Analog Output
are user-defined values that are configured by clicking on the boxes adjacent to each heading.
The following examples show the two different options for configuring the Analog Output.
Example 1 shows the Signal Source set to “Valve Airflow” which is the most common
configuration. Example 2 shows the Signal Source set to “Manual Output” which is typically
used for troubleshooting wiring issues.
