1. A calibration method for a flowmeter delivering an electric pulse signal whose frequency corresponds to the rate of flow of a fluid circulating in a circuit, the method including the steps of:

  • measuring during a data acquisition stage of a specified duration (Ta), each elementary period (T7 (i), T8 (i)) separating two pulses staggered by a specified measurement span;

    counting the number of pulses (n, m) emitted during the acquisition stage (Ta); and

    calculating the mean calibration period (Tm7, Tm8).
