Device for determining liquid level in a container

A level indicator for determining the level of liquid in a container, the level indicator comprising:

• a floating device for being buoyant on the surface of the liquid, the floating device comprising a metal;
• a transmitter arranged to transmit an electromagnetic signal towards the floating device;
• a receiver arranged to receive a response signal from the floating device and to convert the response signal to an electrical signal indicative of the response signal, the response signal from the floating device being caused by the electromagnetic signal, wherein
• 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, wherein
• the receiver is electrically connectable to a control unit so that the electrical signal indicative of the response signal is receivable by the control unit, the control unit is configurable to determine a position of the floating device relative to the receiver based on the electrical signal, to thereby determine the level of liquid in the container.
