1. A system for evaluation of fluid quality comprising:
a vessel containing a quantity of fluid;
at least two acoustic sensors positioned in at least first and second horizontal locations within an interior space of the vessel and fully submerged within the quantity of fluid, the at least two acoustic sensors positioned to emit signals into the quantity of fluid, wherein a fluid identity of the quantity of fluid in the at least first and second horizontal locations is calculatable based on the signals, wherein the at least two acoustic sensors are in direct communication with each other, and wherein the at least two acoustic sensors are configured to communicate a change in the fluid identity to one another;
a temperature sensor configured to sense a temperature of the quantity of fluid; and
a computerized device in communication with the at least one of the at least two acoustic sensors and the temperature sensor, wherein a processor of the computerized device determines a quality of the quantity of fluid based on the fluid identity of the quantity of fluid from the signals from the at least two acoustic sensors at two or more times and the sensed temperature of the quantity of fluid.
