Measurements of small flow rates
Lorenc, Dominik ; Šedivá, Soňa (referee) ; Mancl, Vlastimil (advisor)
The thesis deals with the extension of the laboratory fixtures with a~measuring track designed for the measurement of small fluid flows, on which the thermal flowmeter is tested. The used calibration methods are examined and the track is then subsequently constructed. A~measurement operating program is also developed to set the measurement parameters and to store the measurement data in the required format. The parameters and characteristics of the reference scale used and the thermal flowmeter provided are then measured on the constructed track. The measurement results are presented and the uncertainties of the selected flow rates are determined.

Meter run for servo-actuator test
Hřebíček, Martin ; Bogdálek, Jan (referee) ; Novotný, Zdeněk (advisor)
The aim of this bachelor´s thesis is projecting a metering and regulating run for servo-actuator test, choosing a suitable choice of the soft and accurate regulation of pulsing oil and projecting a suitable armature for holding an constant pressure of an overflow oil. Further to project a suitable kind of pump for supply of operative oil. To verify by calculation of an fitness of a choice of a given armature and choose these elements, which are accessible on Czech market. A projecting of a suitable machine for a detection of lifting of a spindle and a pressure of an impulsive oil to be able to analyze a results and electronically note on a PC output. To draw up a description of process soft measuring and correction of a given servo-actuator.

Automation of track for measurement of water valves characteristics
Lekeš, Pavel ; Havlíková, Marie (referee) ; Šedivá, Soňa (advisor)
My diploma thesis describes upgrade of flowbench serving as test rig for regulation valves characteristic measurement. At the beggining, there is an introduction to the water regulation valves theory followed by current machine condition description. Next chapter defines needed improvements and at the end follows proposition of improvements and necessary component definition and final realization. Final chapter summarizes complete project.

Experimental stand for mechanical heart valves
Ermis, Martin ; Kůrečka, Jan (referee) ; Šedivý, Dominik (advisor)
The thesis focuses on experimental stand for mechanical heart valves. It consists of brief research about cardiovascular system and artificial heart valves. Another part of the thesis is report about measurement made on the stand. This is followed by analysis of other experimental stands in the world and suggestions for improvement of current stand in the laboratory of Victor Kaplan Department of Fluid Engineering.

Measurement of the fans characteristic
Coufalík, Martin ; Štětina, Josef (referee) ; Katolický, Jaroslav (advisor)
This bachelor thesis discusses a fan characteristics and their measurement. The aim of this thesis is to compare the results of measurements, which were done in certified laboratory with results of measurements done in alternative measuring stands. In first part of the thesis are described the basic types of fans and inclusion fans in turbo–machines. Furthermore, the thesis deals with a particular fan, which is part of the combustion system of condensing boiler. This fan is also the object of measurement in practical measurements, which were measured as a part of this thesis. This practical part of the thesis includes also analysis of test track, the measurement procedure and all calculations according to ISO ČSN 5801. At first were carried out measurement in certified laboratory and then in three different measuring stands. In conclusion were these results compared with optimal results.

Software for measuring track
Pikula, Stanislav ; Tomáš, Zůbek (referee) ; Šedivá, Soňa (advisor)
The master's thesis summarizes the theory of flow measurement by differential pressure sensors, especially by Normalized Orifice, and summarizes theory concerning Averaging Pitot Tube. It is briefly described LabVIEW programming environment and flow measuring track for which the software was developed. The thesis describes creation of concept of program and in particular its final realization. The program provide observing actual events on measuring track, saving data to file, detail analysis of stored data and creation of measurement report. The main objective is to determine the Averaging Pitot Tube coefficient.
