The Dwyer AVU Air Velocity Transmitter is ideal for a wide range of HVAC measurement and control applications, particularly in complete building control and energy management systems. The Series AVU Transmitter operates by measuring the heat loss from one of the two sensing elements in the air stream, then calculating the air velocity. Units are virtually immune to drift due to the design of the sensing element, which makes the transmitter accurate over the whole air velocity range.

Applications for the AVU include:

  • Zone control in HVAC systems
  • Supply and exhaust fan tracking
  • Clean room systems
  • Air pollution studies and manufacturing
