Part No. AVLV-2DA1-LCD
Product Overview
The Dwyer AVLV-2DA1-LCD is a duct-mount air velocity transmitter designed for HVAC control applications where the connected controller or building management system requires a standard analog current or voltage input.
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 universal analog output can be configured for 4-20 mA, 0-5 VDC or 0-10 VDC, allowing the transmitter to interface with compatible HVAC controllers and BMS inputs.
A built-in 5-digit LCD provides a local air velocity reading at the transmitter. This is useful during installation, commissioning and troubleshooting because technicians can verify the measured airflow locally and compare it with the analog signal received by the controller or BMS.
Typical response time is about four seconds, or approximately one second under constant temperature conditions. The transmitter is therefore suitable for standard VAV and AHU airflow monitoring and control applications.
The AVLV-2DA1-LCD uses a NEMA 4X (IP66) enclosure and operates from either 24 VDC ±20% or 24 VAC ±20%. Maximum current consumption is 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.
The current output supports a maximum load of 1100 ohms, while the voltage output requires a minimum load resistance of 1 kohm.
For the same analog-output platform without the onboard display, the Dwyer AVLV-2DA1 provides the corresponding no-display configuration.

Frequently Asked Questions
What accuracy does the Dwyer AVLV-2DA1-LCD provide?
The transmitter 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.
What analog outputs does it provide?
The AVLV-2DA1-LCD provides universal analog outputs of 4-20 mA, 0-5 VDC and 0-10 VDC.
What load can the outputs support?
The current output supports a maximum load of 1100 ohms. The voltage output requires a minimum load resistance of 1 kohm.
Does it have a local display?
Yes. The AVLV-2DA1-LCD includes a built-in 5-digit LCD for viewing air velocity readings during installation, commissioning and troubleshooting.
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 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-2DA1-LCD and AVLV-2DA1?
Both models provide the universal analog output configuration. The AVLV-2DA1-LCD adds a built-in 5-digit LCD, while the AVLV-2DA1 does not have an onboard display.
Which model should I choose for Modbus or BACnet communication?
For Modbus RTU/ASCII communication, the Dwyer AVLV-2DM1-LCD is the corresponding LCD-equipped model. For BACnet MS/TP communication, the Dwyer AVLV-2DB1-LCD provides the corresponding BACnet interface. The AVLV-2DA1-LCD is intended for applications where the controller uses standard analog inputs.
