Flow Measurement - oriffice plates
Krátká, Lucie ; Málek, Petr (referee) ; Šedivá, Soňa (advisor)
The aim of the Bachelor thesis is to approximate the fluid flow measurement using differential pressure transducers inserted into fully filled circular cross-section conduits running full in the industrial sector. The introduction of the Bachelor thesis describes and explains the principle of fluid flow measurement using differential pressure transducers and the basic types of primary flow elements. Practical part consists of the design of practical calculations of individual parameters of standardized orifice plates, the design of a program for calculation of these parameters, comparing the achieved results with the output from the program Conval, evaluating these results and analyzing the measurement uncertainties for the parameters that affect the design of the standard orifice plate.

Workplace of flow and pressure measurement
Brabenec, Jiří ; Beneš, Petr (referee) ; Bejček, Ludvík (advisor)
The thesis deals with formation of a workplace for preparation gaseous mixtures and their future usage. The main goal of the thesis is testing of new materials which have suitable usage as catalysts. Gaseous mixture is prepared by calorimetric mass flow meters with control valve and multiposition microelectric valve actuators. The next part describes measuring of pressure and temperature and controlling of furnace temperature. The thesis deals with specifications of all devices, their circuitry, communication and program controlling. All devices are controlled by computer with program which is programmed in LabVIEW.

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.

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.
