Abstract
Process and device for the feeding of fluid additives and, in particular, of replenishers to a photographic processing fluid. Fluid additives are supplied to the processing fluid contained in a photographic processing tank by a feeding duct. The feeding duct is filled with processing fluid before different fluid additives are introduced into the feeding duct. The volume of the fluid additive supplied is measured by a flow meter which is arranged in an area of the feeding duct which during the measuring operation carries only processing fluid and not the fluid additive being fed into the feeding duct.
