SECTION 1 - INTRODUCTION 

The AVR product family integrates a high-performance airflow and temperature controller with 

the revolutionary award winning AccuValve

®

.  Accutrol has applied years of experience, 

technology and innovation to make the AVR AccuValve

®

 not only the most advanced airflow 

control valve in the industry, but also the most reliable and intuitive room airflow and 

temperature control system available. 

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 blade and a static regain section.  As air enters the chambers it accelerates 

and compresses, creating an ideal zone 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 signal generated by each vortex shedding sensor provides a direct measurement of 

the volumetric flow rate in each chamber of the AccuValve®.  The airflow measurement 

provides closed-loop feedback to the ePI

®

 controller which modulates the valve actuator to 

maintain the desired airflow setpoint. 
The AVR combined with the Accutrol Room Temperature Sensor provides the foundation for a 

comprehensive airflow and temperature control system that is designed specifically for critical 

laboratory applications that may include numerous VAV fume hoods within the controlled 

space.  The AVR communicates with the building automation network via EIA-485 supporting 

BACnet MS/TP as a Full Master Node state machine. Field programming is accomplished 

through the AccuValve Insight user-interface software which runs on a Windows 10 computer 

or tablet. Communication between the configuration computer and the AVR is provided 

through a USB connection or through an optional wireless Bluetooth connection.
