Abstract

POSTOPEK ZA MERJENJE DOLŽINE IN APARAT ZA IZVEDBO TEGA POSTUPKA. Po postopku po izumu za merjenje dolžine stolpca tekočine v stolpcu vzpostavi stojno valovanje znane hitrosti razširjanja in se amplitudo stojnega valovanja zaznava pri koncu stolpca, kjer se valovanje uvaja, in se frekvenco valovanja spreminja, dokler se ni zaznalo vsaj dveh zaporednih amplitudnih maksimov ali amplitudnega minima, ki sledi amplitudnemu maksimu, in se ugotovi njim pripadajoče frekvence. V aparatu po izumu za izvajanje opisanega postopka je audiogenerator (1) povezan z vmesnikom (4, 22) katerega drugi konec (8) je nameščen ob odprti konec (5) cevaste votline (6, 29) vsebujoče tekočino, in je sprejemniški mikrofon (7, 24) nameščen v vmesniku (4) ob odprtem koncu (5) votline (6, 29).
