The zero pressure compensation method has proven to be the best method to measure air flow rates accurately although it also has be shown that the accuracy depends on the type of air terminal device and how and where the pressure to be compensated is measured in the instrument. Although the principal of the zero pressure method implies universal applicability, in practice this does not seem to be case. This has lead us to develop the ‘extended’ zero pressure method
