Part Number-AVUL-5DA1-LCD
The Dwyer AVUL-5DA1-LCD is designed for higher-velocity supply and exhaust duct applications where reliable 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 building automation and control systems.
The transmitter features a NEMA 4X (IP66) enclosure, making it suitable for mechanical rooms, plenums, and other demanding HVAC environments. It operates across 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-LCD 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, simplifying installation for both retrofit and new HVAC control projects.
A built-in 5-digit LCD provides convenient local readouts during commissioning and troubleshooting. The compact transmitter mounts into a standard duct probe assembly and carries BTL and CE approvals.
For applications requiring the same high-velocity measurement range without a local display, the AVUL-5DA1 is the corresponding non-LCD model.

Who This Product Is Best For
The Dwyer AVUL-5DA1-LCD is suitable for HVAC controls contractors, BMS integrators, building automation professionals, and facility maintenance teams working with higher-velocity duct systems.
It is particularly useful where technicians need both flexible analog output integration and a local display for commissioning, troubleshooting, and on-site verification.
How to Use
- Mount the AVUL-5DA1-LCD 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, controller, or compatible monitoring system.
- Select the required velocity range: 1000, 2000, 3000, or 4000 FPM.
- Verify the air velocity reading on the 5-digit LCD during commissioning.
- Confirm that the transmitter output is correctly recognized by the connected control system.
Frequently Asked Questions
