为了为透析机提供透析液，将淡水与一种或多种透析液浓缩物混合。 水和浓缩物的混合物借助于配量单元（16）以独立于透析液流量的预定流速输送到补偿室（18）中。 浓缩物的剂量是体积的并且作为通过电导率传感器测量的透析液的电导率的函数来监测。 由于水和浓缩物的混合物总是以相同的流速输送，所以可以高精度地确定透析液的组成，并且可以精确地进行配比。

For the preparation of dialysing fluid for a dialysis apparatus, fresh water is mixed with one or more Dialysierflüssigkeitskonzentraten. The mixture of water and concentrates is conveyed by means of a proportioning (16) regardless of the dialysate in a compensating chamber (18) at a predetermined flow rate. The dosage of the concentrates is carried out volumetrically and is monitored as a function of the conductivity of the dialysis fluid, which is measured by means of conductivity sensors. Since the mixture of water and concentrates is always conveyed the same flow rate, the composition of the dialysis fluid can be determined with high accuracy and the proportions are made accurately.
