ABSTRACT:
The invention relates to a method of and apparatus for calibrating flowmeters which may be employed in a dialysis liquid circuit. The invention includes the steps of measuring during a data acquisition stage of a specified duration (Ta), each elementary period (T.sub.7 (i), T.sub.8 (i)) separating two pulses staggered by a specified time measurement span (P), counting the number of pulses (n, m) emitted during the acquisition stage (Ta), and calculating the mean calibration period.
