THE MASTER'S THESES ON THE ESTIMATION OF METROLOGICAL PROPERTIES OF MEASURING INSTRUMENTS ON THE BASE OF THE EXPERIMENTAL INVESTIGATIONS AND THE MATHEMATICAL MODELLING

Abstract

The students of the Department of Automatic Control, Electronics and Computer Science are preparing their master's theses in Measurement Systems Group of Institute of Automatic Control. They include the experimental investigations in Institute laboratory of various measuring instruments and also the mathematical modelling of primary devices of flowmeters and other instruments. Some results of master's theses were published in Polish scientific newspapers and in international conference proceedings. The measurement system for identification dynamic model of thermometers by "in-situ" method was elaborated. The measurement system enables identification of dynamic models of resistance thermometers by three methods: classical step-input method and two in-situ (internal input) methods. The mathematical modelling of distorted velocity distributions enables the investigation of errors of sampling flowmeters. On the base of the experimental data from rivers the modelling investigations for sampling flowmeter used for open channel were made.
