Part Number: AVUL-5DB1
The Dwyer AVUL-5DB1 is designed for higher-velocity supply and exhaust duct applications, providing air velocity measurement from 1000 to 4000 FPM (5–20 m/s) with 5% of reading accuracy. Its BACnet MS/TP communication enables direct integration with compatible building management systems and HVAC controllers.
The transmitter features four field-selectable velocity ranges: 1000, 2000, 3000, or 4000 FPM (5, 10, 15, or 20 m/s). This allows the device to be configured according to the airflow requirements of different HVAC installations.
A NEMA 4X (IP66) enclosure provides protection suitable for mechanical rooms and plenum environments. The AVUL-5DB1 operates within 32 to 122°F (0–50°C) and supports 5–95% RH non-condensing humidity conditions.
The transmitter has a response time of approximately 4 seconds under typical conditions and 1 second at constant temperature, making it suitable for real-time AHU and fan-control applications. It operates on 24 VDC or 24 VAC with a maximum current consumption of 60 mA.
This variant does not include an onboard display. Air velocity readings are transmitted through BACnet to the connected BMS or controller. Its compact body is designed for mounting with a standard duct probe assembly, while BTL and CE approvals support applicable BMS integration and electrical compliance requirements.
For applications where local monitoring is required, the Dwyer AVUL-5DB1-LCD provides the same high-velocity measurement and BACnet communication capabilities with an integrated 5-digit LCD.
