Abstract:
Linearization display unit will receive pulses from a gear flow meter KRACHT whose frequency corresponds to a flow. The measured value is flow that nonlinearly depends on the temperature and viscosity of the medium. The dependency is described by calibration curves for each flow meter. The task of the diploma thesis is to design, implement, and verify the operation of the display unit, which calculates the actual flow rate from the input data (pulse rate, temperature, viscosity, and flow meter calibration curves). The device will contain a suitable user interface to display all measured values, inputs for connecting measuring sensors, and outputs for transmission of measured data. A part of the device will be a USB interface for configuration and uploading calibration curves from a PC application, which is designed by diploma student.

Abstract:
The thesis is focused on the design of a self-powered sensor for measurement of water flow rate and temperature in water pipelines. The key block of this thesis is the construction of an electric generator powered by excitation with turbulent flow. The generated voltage should power the sensor's circuits and allow water flow rate measurements. Throughout the development, three prototypes of generators powered by turbulent flow were created. Turbulences were not created by an insertion of a bluff body but by inner geometry of the pipeline elements. Maximum power of 10,66 uW was generated at flow rate of 8 m3/h. Afterwards, a prototype of water flow rate and temperature sensor was assembled. Energy self-sufficiency of the device at common flow rates was not achieved using the chosen procedure. The designed flow rate measurement method is suitable for an approximate flow rate estimation.

Abstract:
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.

Abstract:
The main objective of this work is to create a program for automatic operation of measuring test track. The track is used for multi-hole velocity probes calibration. Normalized orifice plate is used as measurement standard. The program requires the user to enter certain information, which are not measured directly e.g. the values of measuring resistors, static air pressure. After entering this information, measurement can be started. The measurements are carried out simultaneously on the both flowmeters and on the thermomether Pt 100. The actual density of flowing medium is calculated from the measured temperature. Because the measurement is parallel, the calibrated flowmeter can be calibrated during the measurement.

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.
