1. An apparatus for measuring liquid volume 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 data representative of the portion of the detected electromagnetic radiation from each of the plurality of sensors and the at least one measured temperature from the temperature sensor, the processor operable to:
compare the at least one measured temperature to a temperature guideline to identify any temperature events associated with the received data;
normalize the received data based on any temperature events associated with the received data; and
convert the normalized data into a signature representative of the electromagnetic radiation detected by the plurality of sensors.
