2.2 Description
The model A2G-20 air velocity meter is used for measuring ow rates
of gaseous media in ventilation and air-conditioning applications. In
addition, the A2G-20 features integrated temperature measurement.
Electrical output signals for both measurands (DC 0 … 10 V or
4 … 20 mA; adjustable at the instrument via jumpers) enable the direct
connection to control systems or the building automation system.
