Part No. AVLV-2DM1-LCD
The Dwyer AVLV-2DM1-LCD is a duct-mount air velocity transmitter designed for integration with building management systems and HVAC control applications. It provides 2% accuracy across field-selectable velocity ranges of 100, 200, 300, or 400 FPM, equivalent to 0.5, 1, 1.5, or 2 m/s.
Modbus RTU/ASCII communication allows the transmitter to connect directly with compatible building management systems and controllers, making it suitable for VAV and AHU airflow monitoring and control applications.
A NEMA 4X (IP66) enclosure provides protection for installation in mechanical rooms and other suitable HVAC environments. The transmitter operates from 24 VDC or 24 VAC power and supports an operating temperature range of 32°F to 122°F (0°C to 50°C).
The AVLV-2DM1-LCD provides a typical response time of approximately four seconds, with faster response under constant temperature conditions. Its onboard 5-digit LCD allows technicians to view local air velocity readings during commissioning, installation, and field verification without requiring a laptop or separate display.
