Analysis, development and research of optimal procedure of airflow speed meuasiring during respiration
The description of basic procedures of gas and liquid flow speed measuring are presented in the work, the applicable procedures for airflow speed measuring are identified. The most suitable measuring procedure is discovered. It is based on the use of Phleish tube and differential pressure transmitter. The functional diagram for registration and signal processing from differential pressure converter is developed.
Keywords: airflow speed, pressure converter, operational amplifier
