Abstract :
Based on the forced expiration modeling, dynamic errors of process parameters measurements for spirometers with transducers of Lilly tube and turbine are calculated. It is shown that when the time constants of transducer are less than 3 ms, these errors for both types of spirometers do not exceed 0,5%.
