20.500.12556/DKUM-83033 Sistem za umerjanje merilnikov pretoka vode diplomsko delo Calibration system for water flow-meters Diplomsko delo obravnava umerjanje merilnika pretoka vode. Njegove tehnične specifikacije so dvomljive, saj proizvajalec navaja zgolj približno število pulzov na liter, v temperaturnem območju vode pri 20°C. Obenem tlak v sistemu in orientacija merilnika pretoka nista definirana. Umerjanje smo izvedli s pomočjo tehtnice in vzporednega zajemanja signalov merilnika pretoka v različnih položajih. Meritve so se izvajale s pomočjo programske opreme LabVIEW. Med izvajanjem meritev je bila naloga merilca zgolj pozicioniranje merilnika in zagon programa. Ugotovili smo, da orientacija bistveno ne vpliva na vrednosti pretoka, vendar je opaženo odstopanje med našimi meritvami in specificiranimi vrednostmi. Calibration of the water flow meter is described in this thesis. Its technical specifications are doubtful, as the manufacturer states only an approximate number of pulses per litre of water at 20°C, while the pressure in the system and the orientation of the flow meter are not defined. The calibration was carried out by using a scale and parallel acquisition of the flow meter signals in different orientations, while measurements were performed using LabVIEW software. During the measurements, the operator’s task was to position the meter and to start the programme. It was established that the flow meter’s orientation isn't affecting the measurements significantly, however a deviation is noted between our measurements and the specified values.
