Air Velocity Transmitter | Series AVU

The Dwyer Series 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 offers 5% accuracy at a surprisingly low cost, with six units covering ranges from 0-785 fpm to 0-3150 fpm, with either 4-20 mA or 0-10 VDC output.

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.
