Pipeline Fluid Flow Measurement

U zadatku za završni rad na temu mjerenje protoka fluida u cjevovodu su odrađena mjerenja u labaratoriju na Građevinskom fakultetu u Rijeci. Mjerenje se odvijalo u zatvorenom krugu koji uključuje: bazen s vodom, cijevi, pumpu s turbinskim mjeračem protoka i ultrazvučni mjerač protoka kao kontrolni mjerni uređaj. Tijekom mjerenja su zabilježene vrijednosti pet različitih protoka i brzina. Nakon dobivenih vrijednosti, podatci su obrađeni u microsoft excelu. Provedbom regresijske analize podataka dobivena su odstupanja prilikom mjerenja. Mjerilo se s dvije različite metode sa ultrazvučnim protokomjerom, a to su V metoda i W metoda. U radu je izložena provedena analiza kao i ostali načini i metode za mjerenje protoka.In the task for the final work on the topic of measuring the flow of fluid in the pipeline, measurements were performed in the laboratory at the Faculty of Civil Engineering in Rijeka. The measurement took place in a closed circuit that includes: a water pool, pipes, a pump with a turbine flow meter and an ultrasonic flow meter as a control measuring device. During the measurement, values of five different flows and velocities were recorded. After the obtained values, the data were processed in microsoft excel. By performing regression analysis of the data, deviations during the measurement were obtained. It was measured with two different methods with an ultrasonic flow meter, namely the V method and the W method. The work presents the performed analysis as well as other ways and methods for flow measurement
