Part Number: AVLV-1DB1
The Dwyer AVLV-1DB1 is a duct-mount air velocity transmitter built for direct integration into a building management system using BACnet MS/TP communication. It provides 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 that protects the electronics in mechanical rooms, plenum spaces, and other 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 is suitable for standard VAV and AHU control loops. It operates on 24 VAC or 24 VDC power with a maximum current consumption of 60 mA.
This variant is supplied without an onboard display. Air velocity readings are transmitted through BACnet and can be monitored through the connected BMS or controller. The compact 6.0 oz body is designed for convenient installation with a standard duct probe assembly.
The AVLV-1DB1 carries BTL and CE approvals and is designed for professional building automation and HVAC control applications.
If local readings are required during commissioning or field verification, the Dwyer AVLV-1DB1-LCD provides the same 1% accuracy and BACnet MS/TP communication with an integrated 5-digit LCD display.
