The system can be used to calibrate the wind speed and wind direction of an ultrasonic anemometer, cup wind speed transmitter, and wind vane. A wind tunnel creates a homogenous airflow.

The calibration process is automated where possible. The software controls the wind tunnel airflow and sensor rotation, takes readings from the reference, and values from the calibrated anemometer. The system allows calibration of instruments without electronic output too – the reading is taken and submitted into the system manually by an operator.
