Abstract
The technical solution discusses the flow meter that measures the volume flow in one direction, and that is synchonisable with other measuring apparatus. Software can be separately installed on any computer that evaluate the results of the respiratory flow system.
The software may provide an analog signal to other software or you can self-assess and export processing, or in the form of "raw data". It also has software more sync options with other measurement reports (via analog signal, hand to knock off keyboard).
Software flow sensor solves the issue supplement or additional calibration spirometric systems and there is possibly a different application.
