The invention relates to an artificial kidney for controlling and maintaining parity of the entering and emerging quantities in the dialysis liquid circuit. The artificial kidney comprises a dialysis liquid circuit having on either side of the haemodialyser a sensor capable of measuring the quantity of the circulating liquid and a pump for displacing the said dialysis liquid. A microprocessor controller for comparing the quantities of liquid circulating in the upline sensor with the quantities of liquid circulating in the downline sensor, the controller is used for maintaining the quantities of liquid circulating in the upline sensor equal to the quantities of liquid circulating in the downline sensor, during the same period, by subjecting the operation of the pump for displacing the dialysis liquid to the result of the comparison determined by the controller.
