A bath container for liquid treatment of a photographic emulsion carrier has a refill bottle which automatically adds fresh liquid to maintain the liquid level. An overflow maintains the maximum liquid level. A pump having an intake as far removed as possible from the refill bottle serves to circulate the liquid. It further serves to forceably remove liquid from the container corresponding to the quantity of emulsion carrier processed. The signal signifying the quantity of processed emulsion carrier is furnished by a selector switch while scanning the emulsion carrier and connects a capacitor to a constant current source in the presence of the emulsion carrier and to a discharge circuit, in turn connected to circuits which energize the exhaust pump operation, in the absence of the emulsion carrier. Further circuits directly connected to the capacitor serve to energize the exhaust pump operation when the voltage across the capacitor has reached a predetermined voltage.
In equipment for liquid treatment of photographic emulsion carriers, said equipment having a bath container for holding liquid for treating said emulsion carriers, said bath container having an overflow for limiting the maximum liquid level therein, an arrangement for adding fresh liquid to said bath container, comprising, in combination, scan means for sensing said emulsion carrier when in said bath container and furnishing a control signal when the quantity of so-sensed emulsion carrier has reached a predetermined quantity;
