Part Number: AVUL-5DM1-LCD
The Dwyer AVUL-5DM1-LCD is a high-velocity duct-mount air velocity transmitter developed for supply and exhaust duct applications where airflow velocities are higher than those typically handled by lower-range AVLV models.
It measures air velocity from 1000 to 4000 FPM (5–20 m/s) with 5% of reading accuracy and provides Modbus RTU/ASCII communication for integration with compatible building management systems and controllers. The field-selectable ranges of 1000, 2000, 3000, or 4000 FPM allow the transmitter to be configured according to the requirements of the HVAC installation.
The transmitter features a NEMA 4X (IP66) enclosure, providing protection suitable for mechanical rooms and plenum environments. It operates within a temperature range of 32 to 122°F (0–50°C) and tolerates 5–95% RH non-condensing humidity.
With a response time of approximately 4 seconds under typical conditions and 1 second at constant temperature, the AVUL-5DM1-LCD is suitable for standard AHU and fan-control applications. It operates on 24 VDC or 24 VAC with a maximum current consumption of 60 mA, making it suitable for both retrofit projects and new installations.
A built-in 5-digit LCD allows technicians to view air velocity readings locally during installation, testing, and commissioning without relying solely on the connected BMS. The compact transmitter body is designed for mounting with a standard duct probe assembly.
The AVUL-5DM1-LCD carries BTL and CE approvals for applicable integration and electrical compliance requirements.
If a local display is not required, the Dwyer AVUL-5DM1 provides the same high-velocity measurement and Modbus communication configuration without the LCD.
