Part No. AVLV-2DM1
The Dwyer AVLV-2DM1 is a duct-mount air velocity transmitter designed for direct integration with building management systems through Modbus RTU/ASCII communication. It provides 2% accuracy across four field-selectable velocity ranges: 100, 200, 300, or 400 FPM, equivalent to 0.5, 1, 1.5, or 2 m/s.
The transmitter features a NEMA 4X (IP66) enclosure for protection in suitable mechanical room and plenum installations. It operates from a 24 VDC or 24 VAC power supply and supports an operating temperature range of 32°F to 122°F (0°C to 50°C), with 5-95% RH non-condensing humidity tolerance.
With a typical response time of approximately four seconds, and around one second at constant temperature, the AVLV-2DM1 is suitable for standard VAV and AHU airflow monitoring and control applications. The compact 6.0 oz design can be installed as part of a standard duct probe assembly.
Unlike the AVLV-2DM1-LCD variant, this model does not include an onboard display. Air velocity readings are transmitted through Modbus to the connected BMS or controller, making it suitable for installations where local display access is not required.
Need a different specification? The Dwyer range also includes the AVLV-2DM1-LCD, which adds an onboard LCD for local air velocity readings.
