Investigation and the design engineering of the stand to measurement of the flow
(Wydawnictwa AGH, 2007) Wiciak, Grzegorz; Kotowicz, Janusz; Około-Kułak, Jan
On the article one represented manners of the measurement of the flow with the weight-method. The main attention was concentrated on the method of the modifying dynamical weighing. Then one discussed the methodics of the design engineering of the stand for the measurement of the flow and calibrations with the method modified. The manner of the design engineering consists in the modelling and the analysis of the uncertainty of the measuring-system before the realization of measurement. On purpose such procedure is the selection satisfactory way of the measurement and the selection of the measuring-apparatus. Instead on purpose analyses of the uncertainty before a realization of stand measurement is the discoverment of possibly values of the uncertainty with which one ought to matter by the choice of given solution of the constructional stand and the measuring-apparatus. In the article one represented the simulatory analysis of the uncertainty before the realization of measurement, dependent from identifying disturbances affecting the accuracy of the measurement. On the article one introduced also selected results of measuring-experiments carried out on the prototype measuring-stand. The measurement became executed on purpose the verification of the assumed course of action during design-time research. The measuring-experiment confirmed that results of design-time (simulatory) investigations did not deviate from the value of results of measurement on the prototype measuring-stand.
