Series AVUL Air Velocity Transmitter

Description: The Series AVUL Air Velocity Transmitter is designed to provide rapid and accurate measurements of air velocity or volumetric flow in both imperial and metric units. Featuring simultaneous current and voltage outputs across all models, this transmitter offers universal inputs to monitoring equipment. Configurable output range, units, and voltage/current output via local DIP switches ensure adaptability to diverse applications. Optional integral display or portable remote display tool provides convenient local monitoring and unit configuration. Available in 3% and 5% accuracy models, the AVUL series caters to various needs. Optional communication protocols such as BACnet MS/TP or Modbus® RTU/ASCII enable daisy-chaining of units, providing comprehensive access to velocity and flow data, including air temperature.
