Abstract (Croatian)

Zadatak ovog rada jest razrada određivanja protočne količine oštrom prigušnicom za potrebe kontrolnih mjerenja i ispitivanja mjerila protoka. U radu je korištena mjerna oprema u Laboratoriju za procesna mjerenja. U radu je sistematiziran pregled metoda mjerenja protoka, zatim prikazana mjerna linija za mjerenje protoka oštrom prigušnicom te prikaz opisa postupka mjerenja. Rad se temelji na normi ISO 5167-2:2003 po kojoj smo proveli proračun mjerenja. U svrhu što bolje usporedbe rezultata, uveli smo dodatno mjerenje protoka pomoću ultrazvučnog protokomjera. U radu su tablično prikazana sva mjerenja, dijagrami kao i proračun mjerenja.

Abstract

The task of this thesis is to determine the flow rates with orifice plate for the purpose of control measurements and tests of flow meter. In this thesis, the measuring equipment from the Laboratory for process measurement is used. The thesis gives systematic review of the methods of flow measurements, shows measurement line for flow measurement with orifice plate and gives the description of the measurement process. The thesis is based on ISO 5167-2:2003 on which we carry out calculation of measurement. In order to better compare results, we introduced additional flow measurement using ultrasonic flow meter. In thesis all measurements, diagrams and calculation of measurements are tabulated.
