Air flow sensors and volume flow meters are suitable for measuring and controlling volume flows in ventilation and air conditioning systems. Volume flow sensors measure the total pressure, the static pressure of the air flow and the average air velocity. Even very low air velocities of up to 1.0 m/s can be measured by a special shape of the sensor.
In combination with the PID controller type A2G-100 you can set up a very efficient and easily adjustable volume flow control of the ventilation or air conditioning system.
With the air flow sensor type A2G-25, the volume flow rate is calculated using the fan constant (K-factor). All K-factors of common manufacturers are already programmed in the menu of the measuring device so that an input can be made without any problems.
