Logging and transmission equipment comprising at least one autonomous measurement sensor, supplied by an electric cell, comprising an emitter able to transmit at various instants at least one value measured by the sensor, and a receiver for gathering the values transmitted by the emitter; the sensor comprises a means of measuring the temperature in the vicinity of the cell; a link is provided for supplying the emitter with the temperature values measured, which emitter is provided so as to transmit, in addition the values of at least one physical quantity, these temperature values measured, at determined intervals, and the receiver is provided so as to store the temperature values measured, estimates the lifetime of the cell by taking account of these measured values, and determine a date for replacing this cell.

A mechanical fluid meter, for liquid or gas, includes an electronic device (E) that has means for metering, and generally also displaying, consumption, said fluid meter including: at least one fluid temperature sensor () near the meter and at least one ambient temperature sensor () where the meter is installed; a connection means between the temperature sensors () and the electronic device (E); and analysis means () for establishing the temperature difference (&#x394;&#x3b8;) between the fluid temperature and the ambient temperature and for taking into account the fluid flow rate value supplied by the meter, said analysis means being programmed so as to display and/or transmit information indicating a meter blockage when the temperature difference (&#x394;&#x3b8;) is higher than a predetermined limit and the flow rate value supplied by the meter is zero.

System for transmitting data for remote logging between a measurement sensor () comprising an electronic circuit with non-synchronized internal clock and a memory for storing at least one value measured at a first instant (t), and a transmitter () suitable for transmitting at a second instant (t) the value or values measured at the first instant (t), and a receiver () synchronized to a reference time base, for gathering the measured values transmitted; the sensor () comprising an electronic circuit suitable for establishing the time difference &#x394;t (t&#x2212;t) between the instants of transmission (t) and of measurement (t) according to the internal clock of the sensor, and the transmitter () transmits, with the value or values measured at the first instant (t), this time difference &#x394;t; and the receiver comprises a circuit for subtracting from the reception instant (T) according to the reference time base, the time difference (&#x394;t) transmitted via the transmitter so as to give the difference (T&#x2212;&#x394;t) as date to the measurements transmitted.
