A machine and method for preparing dialysis fluid for a dialysis machine. Fresh water is mixed with one or more dialysis fluid concentrates. The mixture of water and concentrates is conveyed into an equalizing chamber by a proportioning unit at a predetermined flow rate independent of the dialysate

A machine and method for preparing dialysis fluid for a dialysis machine. Fresh water is mixed with one or more dialysis fluid concentrates. The mixture of water and concentrates is conveyed into an equalizing chamber by a proportioning unit at a predetermined flow rate independent of the dialysate flow rate. Metered addition of the concentrates is performed volumetrically and is monitored on the basis of the conductivity of the dialysis fluid, which is measured by conductivity sensors. Because the mixture of water and concentrates is always conveyed at the same flow rate, the composition of the dialysis fluid can be determined with a high accuracy and the proportioning can be performed accurately.
