Performance testing of air flow sensor

This report presents a measurement study to investigate the accuracy of the Average Pitot Tube (APT) designed by NTU research team and focus the functionality of the APT using close to the damper in order to predict the air flow after the damper, which is common in the industrial applications. The e...
