Influence of flow velocity at the Dumo
Since the Dumo is equipped with an internal sampling fan which provides a constant flow speed. The fan is
also monitored for changes in the performance to ensure a constant flow speed.
In situations with high winds (>5m/s), the surrounding airflow may affect the internal flow
speed of the Dumo and decrease the accuracy of the measurement.
