Abstract
U ovom diplomskom radu opisani su instrumenti za mjerenje brzine strujanja zraka, njihov princip rada, te metode kojima se mjere brzine strujanja zraka unutar određenog poprečnog presjeka vjetrenog provodnika. Cilj rada je usporedba i određivanje točnosti i pogrešaka pojedinih uređaja za mjerenje brzine strujanja zraka pomoću rezultata dobivenih izvođenjem laboratorijskih i terenskih mjerenja. Mjerenja su se izvodila u pet različitih vjetrenih provodnika različitih oblika i promjera pomoću analognog krilnog anemometra, anemometra s lopaticama, termoanemometra TA5, mikromanomera Askania, te manometra u samogradnji sa senzorom SDP – 610, te su se uspoređivala sa rezultatima očitanja digitalnog anemometra PCE – 008 kao referentnog, odnosno umjerenog uređaja. Rezultati, osim međusobnog odnosa očitanja brzina strujanja zraka pojedinih uređaja pri raznim snagama rada ventilatora, prikazuju veću osjetljivost referentnog uređaja na brzinu strujanja zraka s obzirom na ostale uređaje. Rezultati odstupanja i točnosti očitanja pojedinog uređaja variraju u odnosu na referentni uređaj, u ovisnosti o vanjskim uvjetima poput snage ventilatora i veličine vjetrenog provodnika. Kod laboratorijskih i terenskih mjerenja odstupanja mjernih rezultata su manja pri većim presjecima, te najmanja odstupanja od referentnog uređaja u prosjeku daje termoanemometar TA5.
Abstract (english)
In this graduate thesis, the instruments for measuring the velocity of air flow, their working principles, and the methods used to measure airflow velocities within a certain cross section of the wind transducer are described. The aim of the paper is to compare and determine the accuracy and error range of some devices for measuring the velocity of air flow through results obtained by carrying out laboratory and field measurements. The measurements were performed, by using an analog wing anemometer, anemometers with blades, TA5 thermoanemometer, Askania micromanometer and self - construction manometer with SDP – 610 sensor, in five different wind power conductors of different shapes and diameters and compared to the results of readings the digital anemometer PCE – 008 as a reference calibrated device. The results, apart from the mutual relationship of reading the airflow rate of individual devices at various fan power levels, show higher sensitivity of the reference device to the airflow rate with respect to other devices. The deviation and accuracy of the readings of individual devices varies with reference to the reference device, depending on external conditions such as fan power and the size of the wind conductor. In laboratory and field measurements deviations of measurement results are smaller at larger sections, and the slightest deviation from the reference device is TA5 thermoanemometer.
