Part No. AVLV-2DB1
Product Overview
The Dwyer AVLV-2DB1 is a duct-mount air velocity transmitter designed for HVAC monitoring and control applications where airflow measurements are transmitted directly to a compatible building management system rather than displayed locally.
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. With a typical response time of about four seconds and approximately one second under constant temperature conditions, the transmitter is suited to standard VAV and AHU airflow monitoring and control applications.
This version is supplied without an onboard display. Air velocity readings are transmitted through the BACnet MS/TP connection and can be monitored through the connected BMS or controller. This makes the AVLV-2DB1 suitable for installations where measurements are handled centrally and a local display is not required.
The transmitter carries BTL and CE approvals and uses a NEMA 4X (IP66) enclosure for suitable HVAC installation environments. It operates from either 24 VDC ±20% or 24 VAC ±20%, with maximum current consumption of 60 mA. The operating temperature range is 0 to 50°C (32 to 122°F), with 5 to 95% RH non-condensing humidity. The unit weighs 6.0 oz (160 g) and is designed for installation with a suitable duct probe assembly, with airflow parallel to the sensor tip.
For applications where technicians need a local readout during installation or commissioning, the Dwyer AVLV-2DB1-LCD adds a built-in 5-digit LCD to the BACnet platform.

Frequently Asked Questions
What accuracy does the Dwyer AVLV-2DB1 provide?
The AVLV-2DB1 provides ±2% accuracy across its field-selectable air velocity ranges.
What velocity ranges can it measure?
It can be set to 100, 200, 300 or 400 FPM, equivalent to 0.5, 1, 1.5 or 2 m/s.
Does the AVLV-2DB1 support BACnet?
Yes. It communicates over BACnet MS/TP for integration with compatible BACnet-based building management systems and controllers.
Does it have a local display?
No. The AVLV-2DB1 does not include an onboard display. Air velocity readings are transmitted through BACnet and viewed through the connected BMS or controller.
What is the enclosure rating?
The enclosure is rated NEMA 4X (IP66).
What power supply does it require?
The transmitter operates from either 24 VDC ±20% or 24 VAC ±20%, with maximum current consumption of 60 mA.
What approvals does the AVLV-2DB1 carry?
The AVLV-2DB1 carries BTL and CE approvals.
What is the response time?
Typical response time is about four seconds, or approximately one second under constant temperature conditions.
What is the difference between the AVLV-2DB1 and AVLV-2DB1-LCD?
Both models provide ±2% accuracy and BACnet MS/TP communication. The AVLV-2DB1 has no display, while the AVLV-2DB1-LCD adds a built-in 5-digit LCD for local readings and commissioning.
Where can the AVLV-2DB1 be used?
It is designed for duct air velocity measurement in HVAC and building automation applications, including VAV and AHU airflow monitoring and control.
