1. A non-invasive sensing system for monitoring an amount of content in at least one container comprising:

  • a platform for supporting the at least one container;

    at least one holder associated with said at least one container supported by said platform;

    a source for generating a radio frequency signal;

    circuitry in communication with said at least one holder for transmitting the radio frequency signal through said at least one holder into the at least one container and receiving a portion of the radio frequency signal reflected at a content-air interface in the at least one container; and

    circuitry for processing the reflected radio frequency signal and determining the amount of content in the at least one container.
