Gas Flow measurement
 Majvald, František ; Kunz, Jan (referee) ; Beneš, Petr (advisor)
This bachelor's thesis is focussed on thermal flow meters. There are shortly described basic characteristics of flow and basic terms in flow measurement and its opportunities. The principles of operation of thermal flow meters and its implementation is described closely. With sensors developed by the company of IST AG called FS2 and FS7 was done series of measurements, like measurement of time responses, supply demands, and measurements in the view of determining of mathematical models of the sensors. Mathematical models were determined in a few different ways and its dependence on ambient temperature was found. Thanks to measurement were designed universal electric circuit controlled by microcontroller Arduino Mega 2560. Microcontroller keeps sensors in constant temperature difference mode. There were made trial measurements with designed electronics and the suppression of temperature was checked.
