Abstract
Disclosed is a method for counting events occurring during a period T carried out by a mechanical counter including two toothed wheels with the same pitch, the occurrence of an event causing the rotation of each wheel by an angle corresponding to the pitch of the teeth thereof, the method including: counting or calculating, for each wheel at the end of T, the difference in the number of teeth between the initial and final position thereof, the step being at least partially carried out either by an optical unit, requiring the presence on each wheel of at least one marker, or by a unit for measuring the angular displacement of each wheel and associated calculation unit; and calculating the number of occurred events N in accordance with the difference between the values counted or measured and in accordance with the number of teeth of the wheels.
