Abstract

The invention relates to a device for measuring the fluid consumption of a user over a given measurement time, including a volumetric meter (26) connected to a central information processing unit (28). This unit is designed to take a series of readings at successive intervals in said measurement time, so as to compare each reading with a reference value that corresponds to a predetermined nominal consumption threshold and thus from this deduce the quantity consumed over said measurement time corresponding to consumption with a flow rate higher than the nominal consumption threshold.
