1. An apparatus for measuring a volume of liquid in a container, the apparatus comprising:

  • a plurality of light sources disposed and configured to emit electromagnetic radiation toward the container;

    a plurality of sensors optically coupleable to the plurality of light sources, each sensor of the plurality of sensors disposed and configured to detect the electromagnetic radiation emitted by at least a portion of the plurality of light sources;

    a temperature sensor disposed and configured to measure at least one temperature associated with a liquid in the container; and

    at least one processor configured to;

    receive, from each sensor from the plurality of sensors, data representative of a portion of the electromagnetic radiation detected by that sensor;

    receive, from the temperature sensor, data representative of the at least one measured temperature;

    compare the at least one measured temperature to a temperature guideline to identify any temperature events associated with the data received from each sensor from the plurality of sensors;

    adjust the data received from each sensor from the plurality of sensors based on the at least one measured temperature to produce compensated data; and

    convert the compensated data into a signature including a plurality of values representative of the electromagnetic radiation detected by each sensor from the plurality of sensors.
