Part Number-AVUL-3DA1
The Dwyer AVUL-3DA1 is designed for higher-velocity supply and exhaust duct applications requiring accurate air velocity measurement and flexible analog output options. It measures air velocity from 1000 to 4000 FPM (5–20 m/s) with 3% of reading accuracy and provides universal current/voltage analog outputs for connection to compatible BMS systems and controllers.
The transmitter features a NEMA 4X (IP66) enclosure, along with an operating temperature range of 32–122°F (0–50°C) and tolerance for 5–95% RH non-condensing conditions. This makes it suitable for standard mechanical-room and plenum environments.
With a response time of approximately 4 seconds, or approximately 1 second at constant temperature, the AVUL-3DA1 is suitable for responsive AHU and fan-control applications. It operates on 24 VDC or 24 VAC with a maximum current requirement of 60 mA, supporting both retrofit projects and new installations.
This variant does not include a local display. Measurements are instead transmitted through the connected analog output to the BMS or controller. Its compact body is designed to mount into a standard duct probe assembly.
For applications requiring local readings during commissioning or maintenance, the Dwyer AVUL-3DA1-LCD provides the same 3% of reading accuracy and universal current/voltage analog outputs with an integrated 5-digit LCD display.

Who This Product Is Best For
The Dwyer AVUL-3DA1 is suitable for controls contractors, HVAC professionals, BMS integrators, facility management teams, and building automation projects involving higher-velocity supply or exhaust ducts. It is particularly useful where flexible analog output options are required for connection to a compatible controller or BMS.
How to Use
- Mount the AVUL-3DA1 in the duct according to standard probe insertion practices.
- Connect 24 VDC or 24 VAC power and the appropriate universal current/voltage output to the BMS or controller.
- Select the required velocity range: 1000, 2000, 3000, or 4000 FPM.
- Confirm that the transmitted analog signal is being correctly received by the connected BMS or controller.
- Monitor the air velocity reading through the connected control system.
