Abstract
The present invention relates to a level indicator for determining the level of liquid in a container, the level indicator comprising: a floating device comprising a metal; a transmitter arranged to transmit an electromagnetic signal towards the floating device; and a receiver arranged to receive a response signal from the floating device. The floating device is moveable relative to the receiver so that a distance from the floating device to the receiver is altered in response to an altered level of liquid in the container, and wherein the electrical signal is a function of at least said distance. The receiver is electrically connectable to a control unit configurable to determine a position of the floating device relative to the receiver based on the electrical signal. The invention also relates to a system and a tank comprising the level indicator.
