Abstract

Apparat for nøyaktig måling av hastigheten til et elektromagnetisk signal som blir reflektert av passende konstruerte obstruksjoner innenfor en rørformet bølgeleder. Hensikten med oppfinnelsen er å måle tettheten til væske lagret i en tank. Nevnte tank kan eksempelvis være en lastetank for flytende gass om bord på et maritimt fartøy.
