Abstract

U ovom radu cilj je bio projektirati i izraditi tlačnu komoru za ispitivanje mjerila dubine te
provesti sljedivo umjeravanje barem jednog osjetnika. U prvom djelu zadatka dana je
teorijska osnova kojom su opisane mogućnosti i metode mjerenja razine vode. Nakon
toga je dan opis konstrukcijskog rješenja tlačne komore, projektirana tlačna komora je
zrakotijesna do pretlaka 2 bara te se sastoji od pocinčane cijevi nazivnog promjera
32mm i duljine 600mm, lijevanih kapa i brtvenog materijala. Mjerenja su provedena na
mjernoj liniji koja se sastojala od tlačnog kalibratora, barometra, tlačne komore i
predmeta umjeravanja. Predmet umjerevanja je bilo mjerilo razine vode mjernog
područja do 9 metara dubine. Tijekom razrade ovog zadatka korištene su smjernice
prema metodama DKD-R6-1 i EURAMET. Korištena je etalonska mjerna oprema
Laporatorija za procesna mjerenja.

Abstract (english)

The goal of this paper was to design and make a pressure vessel for calibrating depth
sensors and to carry out at least one traceable calibration of a depth sensor. First of all,
the theoritical background and the posibilities and methods of measuring depth and
fluid level is given. Furthemore, the description of the pressure vessel is given, the
designed pressure vessel must be airtight under overpressure od 2 bars and be made
of 600 mm long galvanized steel pipe with a nominal diameter of 32 mm, cast caps and
sealant material. Measurements were done on a measuring line made of a pressure
calibrator, barometer, the designed pressure vessel and the subject of calibration. The
subject od calibration was a depth sensor with a range of up to 9 meters. This paper
was made with DKD-R6-1 and EURAMET guidelines. The reference equipment od the
Laboratory for process measurements was used in this paper.
