The SERIS AVU Air Velocity Transmitter is well suited for measurement and control applications in HVAC, mainly in complete building control & energy management systems. This Transmitter operates by measuring the heat loss from 1 of the 2 sensing elements in the air stream, after calculating the air velocity. These units are virtually immune to drift due to the design of the sensing element, which makes the transmitter accurate over the whole range of air velocity.
