The main objective of this thesis is to get know about introduce the principles of hemodialysis, blood flow measurement methods and the creation the system and peripheral design of blood flow meter. The thesis contains an introduction to hemodialysis, a description of the dialysis monitor, the distribution of ultrasonic flow meters and system design of blood flow meter with a brief description of each function block, circuit diagram of a flow meter and experimental verification of the circuit. There are also the list of components, printed circuit board drawing and technical drawing of the sensor included.

This diploma thesis deals with the assessment of flow measurement method using portable measuring set with the flowmeter used in the field of official measurement in the free surface profiles. This method is a controlled simulation of the required flow through a portable measurement set. This approach is innovative in relation to other methods of official measurement in which direct flow measurement is carried out. The thesis is based on extensive literary research related to elementary element of this assembly – flowmeter. On the basis of individual characteristics, the technical and metrological requirements for both the flowmeter and the other elements of the measuring set are processed. In the context of these findings and the requirements of the official measurement, input sources of measurement uncertainties are further defined and subsequently calculated by this assembly. The findings from this thesis are fully applicable to the practice of institution authorized for the official measurement of the subject method.

This thesis deals with the monitoring of the sewerage system in the city of Brno. In the research part, there is made an overview of the most used measuring equipment for the monitoring of the sewerage system – level meters, flowmeters, automatic samplers. The practical part is devoted to the monitoring of the sewerage system in Brno for partial evaluation of the benefits of the project „Reconstruction and completion of sewerage in Brno“, realized in 2012 – 2014. Measuring campaign has taken place from June to October 2017. In the course of the work, the instalation of measuring equipment and the collection of measured data was done. After finishing measuring campaign, the data were evaluated from different aspects – the number of overflows, the quantity of overflowing water, the dilution ratio and the quantity of discharged pollution. Then, the hydraulic and construction technical assement of the pipelines of sewer network and overflow chambers and assements of the quantity of the rainwater were made. The results of the evaluation were compared with the results of the previous monitoring campaingns and with the data obtained before the project has been realized. Based on this, the benefit of the project was determined.

Main task of the Master Thesis is to study and propose appropriate sensors that can monitor standard operations of small waste treatment plant. This small plants may replace one big central waste water treatment plant, minimizing interference with the human factor and thus reducing the cost of its operation. Master Thesis deals with the sensors for level measurement, air flow, identifying the operator and others. The most important parameter is the quality of drainage water, which can be derived from the amount of ammoniacal nitrogen. This work discusses the possibility of continuous measurements of ammoniacal nitrogen in water and try to select the optimum solution. At the end of the work is carried out experimental measurements are selected ammonia probe to verify the practical features.

This thesis deals with the problem of designing vortex flow meter for a nominal range of 40 l.min-1. It describes the problems of vortex bodies and choice of methods for detection of vortices. The thesis includes solution of various problems in the design, which were published in scientific articles or patents. The following describes the design solution vortex flow meter for the specified range, which uses ultrasonic sensors to vortices detection. The proposed flow meter is calibrated with reference flow meter and compared with commercially produced vortex flow by the TST electronics and Burkert companies, which are designed for the specified ranges.

This work deals with construction of an experimental measuring stand. This stand will be used for research focused on wheel flange lubrication improvement. The construction is based on wheel flange lubrication system Tribotec OK-02. First part treats of rail vehicle dynamics and wheel flange lubrication problematics, second part describes construction itself.

In the first part of master thesis is presented general introduction to district heating system (DHS) and hydraulic calculation for DHS. The next part deals with analysis operation of DHS and the pressure diagram for certain time interval. Subsequently, the thermohydraulic characteristics for the hydraulic main branch (comparing manual calculation with software calculation) and also the selected thermal and hydraulic characteristics for the whole DHS are shown. The last part is focused on the determination of the amount of heat supplied based on the ultrasonic flowmeter and the temperature probes. Subsequently, the computer simulation is also carried out, aiming at approximating the real heat supply from heat source to solved thermal network in winter.

The diploma thesis is focused on sanitary installations. Theoretical part is focused on description of flow meters and their categorization and flow measurement. Calculation and project part is about water suplly, sewerage and pipeline in health care center. Building is located in Brno and it is a reconstruction, which is divided into stages. The part of the building, which is solved in this thesis is 5. stage.

This diploma work deals with description of pressure sewerage networks. First of all is focused on statistical evaluation of pressure sewerage operation in Káraný municipality where was evaluated waste water flow and pressure on sewerage network.

This diploma thesis deals with the development of methods for evaluating retention features of green roofs. For the purpose of this thesis, a rainfall simulator was designed and various types of precipitation were examined. The thesis is divided into two main parts: a theoretical part and a practical part. In the theoretical part, the importance of water retention on green roofs is discussed. In addition, a physical theory related to this topic is included and various rainfall simulators used for scientific experiments in the Czech Republic and abroad are described. The practical part deals with the measurement of droplet size and rainfall simulator design. In this part, the process of measuring the flow and the intensity of rainfall by using scales, flow meter and rain gauge is described. For this purpose, a datalogger was developed by the Faculty of Eletrical Engineering in Brno. Finally, the results are sumarized and recommendations on how to conduct the research in the future are provided.
