Part Number-AVUL-5DA1
The Dwyer AVUL-5DA1 is designed for higher-velocity supply and exhaust duct applications where dependable air velocity measurement and flexible analog integration are required. It measures air velocity from 1000 to 4000 FPM (5–20 m/s) with 5% of reading accuracy and provides universal current/voltage analog outputs for connection to compatible BMS and HVAC controllers.
The transmitter features a NEMA 4X (IP66) enclosure and is suitable for standard mechanical-room and plenum environments. It operates within a temperature range of 32–122°F (0–50°C) and tolerates 5–95% RH non-condensing conditions.
With a response time of approximately 4 seconds, or approximately 1 second at constant temperature, the AVUL-5DA1 is suitable for real-time AHU and fan-control applications. It operates on 24 VDC or 24 VAC with a maximum current requirement of 60 mA, making it practical for both retrofit installations and new HVAC control systems.
Unlike the LCD version, the AVUL-5DA1 is supplied without an onboard display. Measurements are read through the connected BMS or controller, making this model well suited to installations where local display functionality is not required.
The compact transmitter mounts into a standard duct probe assembly and carries BTL and CE approvals.
For applications requiring local measurement verification, the Dwyer AVUL-5DA1-LCD provides the same high-velocity measurement capability with a built-in 5-digit LCD.

Who This Product Is Best For
The Dwyer AVUL-5DA1 is suitable for HVAC controls contractors, BMS integrators, building automation professionals, and facility maintenance teams working with higher-velocity duct systems.
It is particularly appropriate for installations where air velocity measurements need to be transmitted directly to a BMS or controller through universal current/voltage analog outputs without requiring a local display.
How to Use
- Mount the AVUL-5DA1 in the duct using standard probe insertion practices.
- Connect 24 VDC or 24 VAC power according to the installation requirements.
- Connect the universal current/voltage analog output to the BMS or compatible controller.
- Select the required velocity range: 1000, 2000, 3000, or 4000 FPM.
- Confirm that the transmitted signal is being correctly received and interpreted by the connected BMS or controller.
- Verify system operation during commissioning.
