Abstract
A warning system for a fluid mixing system provides for automatically mixing precise concentrations of photographic processing chemistry to be used in an X-ray film processor. The system produces a fresh batch of mixed solution whenever a previous batch has been reduced to a predetermined minimum volume. The warning system includes a first sensing means responsive to the presence or absence of a predetermined quantity of a first fluid contained within a fluid supply as well as a second sensing means responsive to the level of fluid in a reservoir. The warning system also includes first and second indicators to indicate an absence of fluid in the fluid supply and a predetermined low level of mixed fluid in the reservoir.
