Part Number: AVLV-1DB1-LCD
The Dwyer AVLV-1DB1-LCD is a duct-mount air velocity transmitter designed for direct integration into a building management system using BACnet MS/TP communication. It delivers 1% accuracy across four field-selectable velocity ranges: 100, 200, 300, or 400 FPM (0.5, 1, 1.5, or 2 m/s).
The transmitter features a NEMA 4X (IP66) enclosure, providing protection for installation in mechanical rooms, plenum spaces, and typical HVAC environments. It operates across a temperature range of 32 to 122°F (0 to 50°C) and supports 5–95% RH non-condensing humidity.
With a response time of approximately 4 seconds typical, or approximately 1 second at constant temperature, the AVLV-1DB1-LCD is suitable for standard VAV and AHU airflow control applications. It operates on 24 VAC or 24 VDC power with maximum current consumption of 60 mA.
A built-in 5-digit LCD display provides a convenient local readout directly at the transmitter. This makes the unit useful during commissioning, installation, troubleshooting, and field verification without requiring a laptop or separate monitoring device.
The compact 6.0 oz transmitter carries BTL and CE approvals and is designed for professional HVAC control and building automation applications.
If a local display is not required, the Dwyer range also includes the AVLV-1DB1, which provides 1% accuracy and BACnet MS/TP communication without the onboard LCD.
