20.500.12556/DKUM-38913 Vpliv reducirnih ventilov za vodo na rezultat meritve pretoka vodomera The Influence of pressure reducing value on the measurement of water flowrate Naloga je usmerjena v ugotavljanje razlik v meritvah pretoka vode skozi vodomere v različnih vejah cevovoda in pri različnih tlakih nastavljenih z različnimi tipi reducirnih ventilov v posamezni veji. Meritve so izvedene na posebej zato izdelani merilni progi po primerjalni metodi. Vodomeri in manometri so umerjeni v skladu s standardi. Razlik v merjenju pretoka zaradi spreminjajočega se tlaka in posledično pretoka ni bilo zaznati. Sklepamo, da nihče tako uporabnik, kot distributer vodovodnega sistema ni oškodovan ob meritvah pretečene vode z vodomeri zaradi različnih pogojev odjema pitne vode. The aim of this diploma work is to determine differences in measurement of water flow rate through water gauges in different pipeline sections and at different pressures set by different types of reducing valves in individual sections. The measurements are carried out on a special custom made measurement line using comparative method. Water gauges and manometers are calibrated according to standards. No differences in water flow measurement due to changing pressure were noted. It can be concluded that neither the user nor the distributor of water is at loss when flow rate is measured with water gauges under different water supply conditions. pretok vode vodomeri merilna negotovost flow rate water gauge measurement uncertainty true true false [J.
