Methodology for calibration of containers and tanks
Vrátil, Šimon ; Brno, Miroslava Benková, ČMI OI (referee) ; Vdoleček, František (advisor)
This diplomathesis work is dealing with a concept of volumetric calibration of vessels using the volumetric method. The analysis considers current regulations together with influence of uncertainties in measurements. The principal part of the thesis is analysis of metrological uncertainties resulting from application of various volumetric methods during the calibration process. A practical outcome from this research is development of metrological process for calibration of vessels that could be used by the accredited laboratories.

Method analysis for flow measurement by collecting fluid into the volumetric or weighing vessel
Valdová, Klára ; Šafář,, Robert (referee) ; Žoužela, Michal (advisor)
This diploma thesis is concerned with assessment of two methods of gauging the flow rate used in the sphere of official measurements on profiles with an unrestricted water level. This is the method of collecting liquid into a volumetric vessel and the method of collecting liquid into a weighing vessel (pouch). The main purpose of this work was to specify uncertainties determined using method A and B for these two methods of gauging flow rate within the terms of addressing the Metrology Development Plan of the Czech Office for Standards, Metrology and Testing, because these uncertainties were previously determined using older methodology and using less accurate flow rate benchmarks. The entire work is based on extensive experimental measurement of the flow rate, using the assessed methods, executed at the Laboratory of Water Management Research in Brno. The method of collecting liquids into a volumetric vessel was assessed using four various vessel volumes - 9 l, 15 l, 30 l and 50 l. Relative uncertainties determined using method A and B in relation to flow rate are determined for each vessel in the experimental section of this work. Within the scope of this thesis, these uncertainties were also determined for the method of collection of liquid into weighing vessel (pouch), which was assessed for flow rates of from 0,5 l/s to 10,0 l/s.
