1. A level sensing system comprising;

  • a level sensor label configured to be associated with a container containing a material whose level is to be sensed, the level sensor label arrangement having a circuit including;

    a capacitive structure configured to be associated with the container, wherein the capacitive structure is configured as two separate capacitive elements positioned a distance from each other;

    a first inductive element arrangement in an electrical connection with the capacitive structure; and

    a second inductive element arrangement in electrical connection with the first inductive element arrangement and the capacitive structure, wherein the electrical connection of the first inductive element arrangement and the second inductive element arrangement is an electrical series connection through a connector, and wherein the first inductive element arrangement and the second inductive element arrangement are in an electrical connection with the capacitive structure via connector lines.
