Abstract (Croatian)

Na početku ovoga rada navedeno je nekoliko metoda za mjerenje volumnog i masenog protoka. Opisana je mjerna linija koja se temelji na gravimetrijskoj metodi te su na toj liniji obavljena mjerenja. Provedeno je umjeravanje dva mjerila toplinske energije te su prikazani dobiveni rezultati. Mjerenja su provedena za tri različita režima protoka: nominalni protok, 10 % nominalnog protoka i minimalni protok. Detaljno je obrađena mjerna nesigurnost kod umjeravanja gravimetrijskom metodom te su rezultati prikazani sa pripadajućom mjernom nesigurnošću.

Abstract

At the beginning of this thesis a several methods for volume and mass flow rate is described. The measuring line, based on the gravimetric method is described and on this line were measurements performed. It was carried out the calibration of two heat meters and the obtained results were displayed. The measurements were performed for three different flow rates: nominal flow rate, 10 % of nominal flow rate and minimal flow rate. The measurement uncertainty at calibration by gravimetric method is detailly analyzed and the results are presented with corresponding measurement uncertainty.
