Abstract

A method is provided for measuring by means of radar (3) the level of the medium surface (6) in a tank (1), in which a medium (2) is stored, as well as for identifying the status of the empty tank, where the method entails that an electromagnetic signal is transmitted from the radar (3) fixed to the tank roof (4) via an antenna (5) pointing down into the tank, that an echo signal from the medium surface (6) is received by the radar (3), that the level of the medium surface is calculated from a time delay between the transmitted signal and the echo signal, that a number of characteristics of the change with time in the echo signal amplitude during emptying of the tank, based on historical and/or calculated data, are set, that a registered curve of the echo signal amplitude during emptying of the tank is compared with the set characteristics, and that when the tank is essentially empty the status for the empty tank is identified.
