1. A fluid meter configured to perform metrological measurements in a fluid circulation pipe and to communicate information relating to said metrological data, comprising:
a fluid pipe,
at least one metrological sensor configured to perform metrological measurements in the fluid pipe,
a control block configured to receive the metrological measurements and to communicate information relating to said metrological data,
a power supply block configured to supply energy to the control block, the power supply block comprising a first supply path comprising at least one primary cell, and a second supply path, the power supply block further comprising a first switch configured to selectively couple the first supply path or the second supply path to the control block, characterized in that the fluid meter comprises a thermoelectric generator configured to produce electricity from a temperature difference between an exterior of the pipe and the fluid in the pipe, the second supply path being connected to the thermoelectric generator, the second supply path comprising a capacitor and a second switch configured to selectively couple the capacitor and the thermoelectric generator according to a level of charge of the capacitor.
