ABSTRACT:
Bubble detection apparatus and method for a liquid dispensing system includes temperature compensation for increasing accuracy of the bubble detection as temperature of the liquid varies. In one embodiment, temperature changes cause corresponding changes in the liquid viscosity. A reference value or pressure signal that is used in a comparator circuit is adjusted or compensated for temperature changes of the liquid. The comparator compares pressure signals to the reference to detect bubbles in the liquid being dispensed.
