Product Description
The DWYER AVUL-3DA1-LCD air velocity transmitter accurately measures air velocity or volumetric flow in imperial or metric units. Simultaneous current and voltage outputs provide universal inputs to monitoring equipment. The output range, units, and 0 to 5/10 VDC output can be configured via local DIP switches.
- Measures air velocity or volumetric flow
- Configurable output range and units
- Optional integral display for local monitoring
Product Highlights
The AVUL series air velocity transmitter is designed for use in VAV systems, building ducts, and HVAC systems.
