Description
The Dwyer AVUL Series Air Velocity Transmitter is engineered to accurately measure air velocity in ducts and ventilation systems using a precision thermal sensing element. It supports field-selectable velocity ranges up to 4000 FPM (20 m/s) and offers accuracy options of ±3% or ±5% of reading depending on the model. The transmitter provides simultaneous analog outputs including 4–20 mA and voltage signals (0–5 V or 0–10 V), enabling easy integration with PLCs, BMS, and HVAC controllers. Configuration is simple, with DIP switch settings and digital push-button controls for zero adjustment and parameter setup. Its sensor is designed for stable long-term performance in clean air and inert gas environments.
In addition, the AVUL Series features a rugged NEMA 4X (IP66) enclosure, making it suitable for demanding industrial and commercial environments. It offers fast response time (around 10 seconds) and supports optional BACnet MS/TP or Modbus communication for advanced system integration and networked monitoring. Some variants include an LCD display for local readout and diagnostics, improving usability during installation and maintenance. With its combination of accuracy, flexibility, and robust design, the AVUL Series is widely used in modern HVAC airflow control systems.
