Air flow sensors and air flow meters are suitable for the measurement and control of air flows in ventilation and air-conditioning. Air flow sensors are easy to install and measure the total pressure, the static pressure of the air flow and the average air velocity. In combination with the model A2G-100 PID controller, the user has efficient volume flow control of the ventilation or air conditioning system.
The air flow meters of the model A2G-25 determine the volume flow using a configurable fan constant (K-factor) for all common manufacturers. The electrical output signals of 0...10 V or 4 ... 20 mA can be selected directly in the instrument using jumpers.
