Abstract
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 (3) near the meter and at least one ambient temperature sensor (4) where the meter is installed; a connection means between the temperature sensors (3, 4) and the electronic device (E); and analysis means (5) for establishing the temperature difference (Δθ) 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 (Δθ) is higher than a predetermined limit and the flow rate value supplied by the meter is zero.
