Abstract
A method and system for switching the dispensing of a first solution from a first vessel to dispensing a second solution from a second vessel when a parameter of the first solution crosses a threshold is described. In one embodiment, a fluid dispensing apparatus includes a first vessel and a second vessel. The first vessel includes an output conduit adapted to dispense the first solution from the first vessel into a fluid receiving region. The second vessel includes an output conduit adapted to dispense the second solution from the second vessel into the fluid receiving region. The apparatus includes a first sensor positioned to measure a parameter of the first solution before the first fluid enters the fluid receiving region. The apparatus also includes a second sensor positioned to measure a parameter of the second solution before the second solution enters the fluid receiving region.
