Valve for a pressurised fluid reservoir

A valve for a fluid reservoir, comprising:

• an inner portion configured to be arranged inside the reservoir, the inner portion including at least one portion of at least sensor for measuring at least one parameter characterizing the fluid, the valve being capable of receiving information from an external computer, the external computer being external to the valve;
• and
• an outer portion configured to be arranged outside the reservoir, the outer portion comprising an internal computer comprising:
• a first acquisition means configured to acquire data from the at least one sensor,
• a communication means using a wired digital communication interface configured to communicate bidirectionally with the external computer,
• a control means configured to take into account information received from the external computer and data from the at least one sensor for controlling at least one actuator of the valve, the at least one actuator being connected to the control means by at least one electrical connection,
• a measuring means for measuring at least one current parameter in the electrical connection, and
• a calculation module configured to process the data from the at least one sensor, to process the data from the at least one actuator of the valve, and to format the data processed by the calculation module in a format that can be used by the external computer.
