Abstract
A method of monitoring a fluid meter is arranged to produce measurements of the overall consumption of an installation. The method includes the steps of: analyzing the overall consumption measurements to identify a mechanism in the installation that operates with operating cycles, each presenting a substantially constant cycle duration (t1−t0) and during each of which the individual consumption (V1−V0) of the mechanism is substantially constant; detecting operating cycles of the mechanism and measuring the individual consumption of the mechanism for each detected operating cycle; detecting abnormal metrological drift of the measuring device as a function of variation over time in the individual consumption.
