Measurement system for laboratory of experimental biology
Zálešák, Marek ; Klusáček, Stanislav (referee) ; Čejka, Miloslav (advisor)
There is a breif description of the Lab VIEW from National Instruments in the following text. It also describes the connection measuring cards through different types of buses on the PC. There is also information about the aquatic condition of plants as well as arrangements which will be implemented on the equipment generated during this work. In other parts of the text there is analysed the implementation of measurement and control pressure in the plant and flow measurement weighing using the LabVIEW 8.2

Gas Valve Test Rig
Šefránek, Adam ; Šedivá, Soňa (referee) ; Beneš, Petr (advisor)
This bachelor thesis deals with the innovation of gas valve test rig. First part describes construction, parameters and usage of the original device. Second part determines requirements on a new device and subsequently submits a proposal to meet these requirements. Process of inovation, related problems and differences between final solution and proposal are covered in third part. Last part brings results of test measurement.

Thermal Mass Flowmeter
Mlčoch, Albert ; Kunz, Jan (referee) ; Beneš, Petr (advisor)
The thesis deals with the design of a mathematical model and practical implementation of a flowmeter based on the thermal principle. The range of the proposed flowmeter is from units of kilograms per hour to lower hundreds of kilograms per hour. The design of the flowmeter is non-invasive to the flow channel, the heating element is located outside the pipe. In this paper, the flowmeter parameters are identified and a temperature regulator is proposed. Measurements are made on a test bench. The results of the measurements are discussed. Modifications to the existing hardware are suggested.

Automated measurement system for ethene polymerization
Janošík, Zdeněk ; Richtera, Lukáš (referee) ; Přikryl, Radek (advisor)
Thanks to macromolecular chemistry development polymers become essential materials for wide range of applications. Research of catalytic systems used for production of polymers plays a key role in development of new polymer-based materials. The aim of this work was to develop system providing automated kinetic measurement of catalytic systems used in ethylene solution polymerization. The theoretical part of the thesis provides basic overview on chemical process taking part in ethylene polymerization and technical instruments used for its automation. Description of the devised system, its technical solutions and performed experiments used for verification its proper function are presented in the experimental part. Acquired data were compared with published results obtained with the same catalytic systems. Texts are accompanied by schemes, screenshots and photos.

Flow measurement using the compound weir
Sedlák, Daniel ; Duchan, David (referee) ; Žoužela, Michal (advisor)
Bachelor’s thesis is focused on issues of measurement significantly unstable by the flow rates with using of compound sharp crested weirs. The laboratory research determined three selected types of weirs. Laboratory research have been established three capacitive dependence of selected types of weirs. These dependencies are presented in tabular and graphical form.

Full-width thin-plate rectangular weir influenced by channel width
Zmítko, Jakub ; Roušar,, Ladislav (referee) ; Zachoval, Zbyněk (advisor)
The diploma thesis deals with the propagation of a weir (channel) width on the weir capacity. The influence rate is analyzed by laboratory measurements on models with a weir (channel) width of 0,02 m to a width of 0,50 m. Different heads are analyzed and different discharges that calculate the discharge coefficient. The results are compared with previous works, especially with the work of Kindsvater and Carter (1957) and of Schoder and Turner (1929), where the same procedures are used to calculate discharge coefficients. The thesis contains a theoretical introduction to the problem of thin-plate weirs and the problem of the formation of the boundary layer in the flow of liquid, following with the analytical part. In the analytical part, the results of measurements, their comparison, and evaluation are published. The work is completed with evaluation and recommendations.

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.
