Part No. AVLV-2DM1
Product Overview
The Dwyer AVLV-2DM1 is a duct-mount air velocity transmitter designed for HVAC monitoring and control applications where measurements are transmitted directly to a building management system or compatible controller rather than viewed on a local display.
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 VAV and AHU airflow monitoring and control applications.
Unlike the AVLV-2DM1-LCD, this version has no onboard display. Air velocity readings are intended to be monitored through the connected BMS, controller or building automation system. This makes it suitable for installations where a local readout is not required.
The transmitter uses a NEMA 4X (IP66) enclosure and operates from either 24 VDC ±20% or 24 VAC ±20%. Maximum current consumption is 60 mA. It operates from 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 installed with airflow parallel to the sensor tip.
For applications where technicians need to see the airflow reading locally during commissioning, the Dwyer AVLV-2DM1-LCD provides the same Modbus platform with an onboard 5-digit LCD.

- Connect the Modbus communication wiring to the compatible BMS, controller or building automation system.
- Configure the required velocity range and communication parameters as applicable to the connected system.
- Verify that the air velocity signal is being received correctly by the BMS or controller.
Frequently Asked Questions
What accuracy does the Dwyer AVLV-2DM1 provide?
The AVLV-2DM1 provides ±2% accuracy across its field-selectable 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-2DM1 support Modbus?
Yes. It supports Modbus RTU/ASCII communication for integration with compatible building management systems and controllers.
Does the AVLV-2DM1 have a local display?
No. This model does not have an onboard display. Air velocity readings are transmitted to the connected BMS or controller.
What is the enclosure rating?
The enclosure is rated NEMA 4X (IP66).
What power supply does it require?
The AVLV-2DM1 operates from either 24 VDC ±20% or 24 VAC ±20%. Maximum current consumption is 60 mA.
What is the response time?
Typical response time is about four seconds. Under constant temperature conditions, response time is approximately one second.
Where can the AVLV-2DM1 be used?
It is designed for duct air velocity measurement in HVAC and building automation applications, including VAV and AHU airflow monitoring and control.
What is the difference between the AVLV-2DM1 and AVLV-2DM1-LCD?
Both models provide ±2% accuracy and Modbus RTU/ASCII communication. The AVLV-2DM1 has no local display, while the AVLV-2DM1-LCD adds an onboard 5-digit LCD for viewing air velocity at the transmitter.
