1. A prediction method for predicting freezing of a liquid flowing in a pipe of a liquid meter, wherein the liquid meter is used for measuring the consumption of liquid supplied by a distribution network to an installation of a client, the method comprising the steps of:
acquiring measurements of air temperature in the liquid meter;
from the air temperature measurements, evaluating an air temperature prediction parameter representative of future variation of the air temperature;
from the air temperature prediction parameter, evaluating a liquid temperature prediction parameter representative of future variation of liquid temperature;
using the liquid temperature prediction parameter to estimate a duration-to-freezing between a present instant and an instant at which the liquid risks freezing;
generating an alarm if the duration-to-freezing is less than a predetermined time threshold.
