Monitoring method for monitoring a set of meters

A monitoring method for monitoring a set of meters, each meter being arranged to measure a stream supplied to an installation by a distribution network, all of the meters being connected to a common remote processor device, the monitoring method comprising both first steps performed in each meter, for:

• acquiring primary measurements of a magnitude representative of the occurrence of an anomaly associated with said meter;
• selecting pertinent measurements from the primary measurements, the pertinent measurements satisfying a pertinence criterion;
• regularly transmitting the pertinent measurements to the remote processor device;
• and second steps performed in the remote processor device, for:
• comparing, for each meter, the pertinent measurements with a detection threshold common to all of the meters of the set of meters in order to attempt detecting an anomaly associated with said meter;
• determining a percentage of meters detected as being associated with an anomaly among all of the meters;
• adjusting the detection threshold dynamically as a function of the percentage of meters detected as being associated with an anomaly,
• wherein, when the percentage of meters detected as being associated with an anomaly is greater than a first predetermined percentage, the remote processor device increases the detection threshold so that the percentage of meters detected as being associated with an anomaly becomes less than or equal to the first predetermined percentage.
