Part Number: AVLV-1DM1
The Dwyer AVLV-1DM1 is a duct-mount air velocity transmitter built for direct integration into a BMS or controller through Modbus RTU/ASCII communication. It delivers 1% accuracy across four selectable velocity ranges: 100, 200, 300, or 400 FPM (0.5, 1, 1.5, or 2 m/s).
Its NEMA 4X (IP66) enclosure provides protection for installation in mechanical rooms, plenum spaces, and other typical HVAC environments. The transmitter operates from 32 to 122°F (0 to 50°C) and tolerates 5–95% RH non-condensing humidity.
With a typical response time of approximately 4 seconds, or approximately 1 second at constant temperature, the AVLV-1DM1 is suitable for standard VAV and AHU control applications. It operates on 24 VDC or 24 VAC power, with maximum current consumption of 60 mA.
This version is supplied without a local display. Air velocity readings are transmitted through Modbus and can be monitored through the connected BMS or controller. The compact 6.0 oz design makes it practical for duct-mounted HVAC applications.
The AVLV-1DM1 carries BTL and CE approvals and is designed for professional HVAC control and building automation applications.
If your application requires a local display, the Dwyer AVLV-1DM1-LCD provides the same 1% accuracy and Modbus communication with an onboard LCD display.
