Method and device for determining the level L of a liquid within a specified measuring range by means of radar signals transmitted to the liquid surface and radar signals reflected from the liquid surface

摘要

The invention relates to a method for determining the level L of a liquid within a specified measuring range by means of radar signals transmitted to the liquid surface and radar signals reflected from the liquid surface, comprising the steps of i) transmitting radar signals to the liquid surface in time sequence; ii) receiving radar signals reflected from the liquid surface in time sequence; iii) determining the level L partially on the basis the transmitted radar signals and the reflected radar signals. The invention further relates to a device for determining the level L of a liquid within a specified measuring range, at least comprising a radar antenna disposed above the liquid for transmitting radar signals to the liquid and receiving radar signals reflected from the liquid surface, as well as means for determining the liquid level L on the basis of the transmitted radar signals and the reflected radar signals.
