1. A flammable fluid meter, comprising:
a first communication interface arranged both to communicate via a radio link with a second communication interface of a cut-off unit including an electromechanical valve, and also to transmit electrical energy via the radio link, the electrical energy being adapted to power the second communication interface of the cut-off unit;
a temperature sensor arranged in the flammable fluid meter to measure a temperature of the flammable fluid which is in the flammable fluid meter; and
a processor module arranged to acquire temperature measurements produced by the temperature sensor, to attempt to detect an occurrence of an anomaly relating to the temperature of the flammable fluid, and if an anomaly relating to the temperature of the flammable fluid is detected, to produce an internal control frame incorporating a closing command for closing the electromechanical valve and to transmit said internal control frame to the second communication interface of the cut-off unit via the first communication interface in order to close the electromechanical valve.
