This paper presents the advantages of using upstream and downstream stagnation pressures instead of static pressures to determine the flow characteristics of a pneumatic component. A proposal to measure directly stagnation pressures (sum of static and dynamic effects) is compared to the use of calculation to obtain the stagnation pressure from static pressure measurement. The use of an expanded section to measure directly the downstream stagnation pressure enables to obtain the whole conductance curve of the component, making easier the parameters determination.
