The AFD-1 instrument has been designed for the measurement of air velocity and air flow. It has a 4-digit display and a voltage or current output propotional to the airflow. The display and output scaling can be programmed for air velocity (m/s) or volume flow (m3/s) by push- button keys inside the instrument. As an option AFD-1 also might have two adjustable limit switches which can be used as alarm or ON-OFF control operation.
