Abstract:
V diplomski nalogi je predstavljena izvedba akustičnega merilnika tekočin na osnovi spektralne analize akustičnega valovanja, ki se ustvari v resonatorju. Merilnik temelji na vzbujanju resonančne cevi s šumnim signalom ter FFT analizi valovanja, ki se ustvari v resonančni cevi ob takšnem vzbujanju. Opisan je teoretični princip delovanja, zasnova in razdelitev vezja ter blokovna struktura celotnega programa. Kot osnova teoretske analize so obravnavani pojmi valovanje v zaprti piščali, harmoniki, frekvenčni spekter, FFT analiza. Prikazani so tudi rezultati meritev pri petih različnih temperaturah in karakteristike resonatorja.

Title:
FLUID LEVEL GAUGE BASED ON SPECTRAL ANALYSIS OF ACOUSTIC WAVES
Abstract:
The diploma thesis presents realization acoustic fluid level gauge based on spectral analysis of acoustic waves, that is created in resonator. The level gauge is based on excitation of resonant pipe with noise signal and analysis of acoustic waves FFT, that is created in resonant pipe on such excitation. Theoretical principle of activity, design, distribution of circuit and block structure of entire program is described. On the base of the theoretical analyze notions such are waves within a closed whistle , accordions, frequency spectrum, FFT analysis were discussed. The results of measurements at five different temperatures and features of resonator were also showed.
