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.Apparatus for accurately measuring the velocity of an electromagnetic signal reflected by suitably constructed obstructions within a tubular waveguide. The object of the invention is to measure the density of liquid stored in a tank. Said tank may, for example, be a cargo tank for liquefied gas on board a maritime vessel.
