Dwyer AVUL [AVUL-3DA1] Air Velocity Transmitter, 0-5 V, 0-10 V, 4-20mA, 3% Accuracy

The Dwyer AVUL-3DA1 Air Velocity Transmitter, 0-5 V, 0-10 V, 4-20mA, 3% Accuracy  offers air velocity or volumetric flow of clean air and non-combustible, compatible gases. Simultaneous current and voltage outputs on AVUL models provide universal inputs to monitoring equipment while the output range, units, and 0 to 5/10 VDC output can be configured via local DIP switches. Zero and span adjustments can be made via digital push buttons.

Dwyer AVUL Series air velocity transmitters are available with a standard 5% accuracy or a 3% optional upgrade. The optional integral display on the AVUL series provides a convenient way to locally monitor process values and configure the unit. Additionally, optional BACnet MS/TP or Modbus® RTU/ASCII communication protocol allows units to be daisy-chained while providing access to all of the velocity and flow data, as well as additional information such as air temperature.
