SERIES AVUL AIR VELOCITY TRANSMITTER
The Series AVUL Air Velocity Transmitters quickly and accurately measuresair velocity or volumetric flow in imperial or metric units. Simultaneous current andvoltage outputs on all models provide universal inputs to monitoring equipment whilethe output range, units, and 0 to 5/10 VDC, 4-20 mA output can be configured via localDIP switches. The optional integral display, or the portable remote display tool, providea convenient way to locally monitor process values and configure the unit.Models are available in 3% and 5% accuracy models to suit a variety of needs, and theoptional BACnet MS/TP or Modbus® RTU/ASCII communication protocol allows unitsto be daisy-chained while providing access to all of the velocity and flow data, as wellas additional information such as air temperature.
Product Applications
- VAV systems
- Building ducts
- Sensing elements have been coated with an engineered conformal coating to ensure durability and longevity
- Field selectable ranges can be quickly configured without power to the unit
