An apparatus for measuring doses of dispensed products includes a first metering ring (20) mounted to rotate 5 around a rotation axis (1), and drive means (10) that drives the first metering ring to rotate around an axis (1). The drive means (10) is actuated each time the dispenser is actuated. The apparatus also has interlocking means (15, 22) that engage the drive means (10) with the first metering ring (20) after the dispenser has been actuated a predetermined number of times. The first metering ring (20) is driven to rotate once it is engaged with the drive means (10). The apparatus only counts the doses of dispensed product after the dispenser has been actuated a predetermined number of times. |
