PITOT-STATIC TUBE OR PITOT TUBE FOR MEASURING FLOW RATES?

Eddy Jacques, Pierre Wauters

Abstract

Where volume flow rates in ventilation applications are to be measured common practise is to integrate the velocity profile over the entire cross-section. One of the instruments used to carry out the flow velocity traverse is the Pitot-static tube. The paper examines, on an experimental basis, whether the readings of both total and static pressure by a Pitot-static tube could not validly be carried out by a combination of a Pitot tube that measures the total pressure and tappings at the wall of the duct where the static pressure is picked up. The advantage becomes particularly interesting for applications where the flow rate may change in time.
