Averaging Air Velocity Sensor(AAVS)
The Averaging Air Velocity Sensor™ (AAVS) is a high-accuracy airflow measurement sensor designed for Ecogate systems using the greenBOX (Adelie-generation). It continuously measures air velocity in the main duct by sampling across the duct cross-section and averaging the results, delivering reliable real-time airflow and velocity data directly to the control system.
This data improves system regulation, simplifies recalibration after system changes, and supports compliance with minimum conveying velocity requirements.
How It Works
The AAV Sensor operates on the same measurement principle as a pitot tube, but without manual traversing.
Instead of taking single-point readings, the sensor simultaneously measures air velocity at 24 to 46 points across the clean-side duct. These measurements are averaged to produce a highly accurate representation of actual duct velocity and airflow.
Once installed, the greenBOX Controller displays real-time duct velocity and airflow values, providing continuous visibility into system performance.
Key Benefits
-
High-accuracy airflow measurement
Averaged multi-point sensing delivers more reliable data than single-point velocity measurements. -
Maintains minimum conveying velocities
Helps ensure duct velocities remain above required thresholds, reducing the risk of dust settling. -
Improved system safety
Early detection of low velocity conditions can indicate blockages or flow issues before they become hazards. -
Supports NFPA compliance
Assists Ecogate controls in maintaining minimum conveying velocity requirements per NFPA 664. -
Simplifies system changes
Ideal for facilities planning duct resizing, machine rearrangements, or airflow recalibration.
-
System Compatibility

Why Add the AAV Sensor
Accurate airflow data is foundational to safe, efficient dust collection. The Averaging Air Velocity Sensor provides the real-time feedback needed to keep velocities in range, validate system performance, and respond quickly when conditions change.
For facilities that care about airflow accuracy, safety margins, and long-term reliability, this sensor closes an important measurement gap.
