Part No.: AVLV-1DM1-LCD
The Dwyer AVLV-1DM1-LCD Air Velocity Transmitter is a duct-mount air velocity transmitter designed for direct integration into building management systems through Modbus RTU/ASCII communication. It provides 1% accuracy across field-selectable velocity ranges of 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 installations in mechanical rooms, plenum spaces, and typical HVAC environments. It operates across 32 to 122°F (0 to 50°C) and supports 5–95% RH non-condensing humidity.
The AVLV-1DM1-LCD has a typical response time of approximately 4 seconds, or approximately 1 second at constant temperature, making it suitable for standard VAV and AHU control applications. It operates on 24 VDC or 24 VAC power with a maximum current consumption of 60 mA.
A built-in 5-digit LCD provides a local air velocity readout directly at the transmitter. This makes commissioning, troubleshooting, and field verification easier without requiring a laptop for local measurement checks.
The compact 6.0 oz body is designed for installation with a standard duct probe assembly. BTL and CE approvals support its use in building automation and general electrical applications.
The Dwyer range also includes the AVLV-1DM1, which provides Modbus communication without the onboard LCD. Contact GeneralTech Shop if you need help selecting the correct variant for your application.
