Estimation of a deleted fluid consumption
First Claim
1. A method for estimation of a deleted fluid consumption during a deletion phase, said method implemented by computer means comprising:
- during a learning phase;
a first collection step which consists of collecting first consumption data comprising information about the consumption of fluid from n fluid meters coming from a first group, where n is a positive integer and where said n fluid meters from the first group have subscribed to a deletion service;
a second collection step which consists of collecting second consumption data comprising information about the consumption of fluid from m fluid meters coming from a second group, where m is a positive integer and where said m fluid meters from the second group have not subscribed to a deletion service;
a step of analysis of the first and second collected consumption data during which weighting coefficients β
i are calculated as a function of these first and second consumption data so as to minimize the distance between the fluid consumption of the first and second groups, where i is a positive integer included between 1 and m; and
a determination step during which a control group is determined from the second collected consumption data coming from m fluid meters from the second group and as a function of the weighting coefficients β
i calculated during the analysis step; and
during the deletion phase;
an estimation step consisting of estimating the deleted fluid consumption during a deletion phase by calculating the difference between the fluid consumption of the control group and the average fluid consumption of the n fluid meters from the first group.

Abstract
A device for estimating a deleted fluid consumption during a deletion phase, where said device comprises: a collection module configured to collect: a) first consumption data comprising information about the consumption of fluid from n fluid meters coming from a first group, and b) second consumption data comprising information about the consumption of fluid from m fluid meters coming from a second group, a computer analysis module which is configured for calculating, as a function of the first and second consumption data weighting coefficients βi minimizing the distance between the fluid consumptions of the first and second groups, where i is a positive integer included between 1 and m.
