Abstract
A fluid meter has a first communication interface and is connected to the cut-off unit having a communication interface. If the fluid flow rate remains greater than a first predetermined flowrate threshold for at least a first predetermined duration, to detect that there is a leak of fluid and to transmit an internal command frame incorporating a closing command to the communication interface of the cut-off unit. Following closing of the electromechanical valve, to acquire a first external command frame incorporating an opening command produced by the cut-off unit following manual action on an actuator member of the cut-off unit, to produce an internal command frame incorporating the opening command, and to transmit said internal command frame via the first communication interface to the communication interface of the cut-off unit in order to reopen the electromechanical valve.
