A level sensing apparatus and method of use for use with a beverage server to indirectly sense the level of beverage retained in the server. The server having a body for receiving and retaining beverage with an opening in the body for receiving the level sensing apparatus and beverage there through. The level sensing apparatus includes at least one capacitive sensing probe assembly retained in a housing to separate the probe assembly from contact with beverage. The housing containing the capacitive sensing probe assembly being disposable into the opening in the body of the server. The capacitive sensing probe indirectly sensing at least one level of beverage retained in the beverage server. A separate display assembly is provided and selectively couplable to the capacitive sensing probe assembly. A power source is provided and coupled to the display assembly and to the capacitive sensing probe assembly to provide power to sense and display the level of beverage in the server.
