The dialysis liquid circuit comprises a supply line (11) for the supply of fresh dialysis liquid, said line being connected to an inlet of a first compartment (2) of a dialysing apparatus (1), the line being provided with first means (14) for measuring a dialysis liquid characteristic such as a first flowmeter ; a discharge line (13) for the spent liquid, said line being connected to an outlet of the first compartment (2) of the dialysing apparatus (1), the line being provided with second means (16) for measuring a dialysis liquid characteristic, such as a second flowmeter; bypass means (20, 21, 22) for connecting on demand the supply line (11) to the discharge line (13) so as to set the measuring means (14, 16) directly in series; and means (18) for calibrating the measuring means (14, 16); and a buffer tank (23) for the spent liquid, said tank being arranged on the discharge line (13) upstream of the second measuring means (16) in order to provide for the circulation of spent liquid upon contact with the second measuring means (16) when the supply (11) and discharge (13) lines are connected by the bypass means at least during the time required for calibrating the measuring means (14, 16). |
