Series AVLV Air Velocity Transmitter
1% and 2% Models, Optional BACnet MS/TP or Modbus®
The Series AVLV Air Velocity Transmitter quickly and accurately measures air velocity or volumetric flow in imperial or metric units. Simultaneous current and voltage outputs on all models provide universal inputs to monitoring equipment while the output range, units, and 0-5/10 VDC, 4-20 mA output can be configured via local DIP switches. The optional integral display, or the portable remote tool, provide a convenient way to locally monitor process values and configure the unit.
Models are available in 1% and 2% accuracy models and low velocity ranges to suit a variety of needs, and the 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. The lower ranges in these high accuracy units allow for applications in quality intensive environments, such as the pharmaceutical industry.
