Valve system e.g. microelectromechanical system, for cylinder of pressurized fluid e.g. gas, has command units connected to data processing unit for commanding control units to control fluid flow according to data relative to fluid

摘要

The system has digital data acquisition units (12) e.g. piezoelectric sensor, for acquiring digital data such as fluid pressure (P1) in the cylinder, downstream fluid pressure and fluid mass flow (Dm), relative to pressurized fluid. A digital data processing unit processes the data, and fluid flow control units comprise a pressure reducer (14), a fluid mass flow regulator (17) and an isolating valve (19). Command units are connected to the processing unit for commanding the control units to control the fluid flow according to the data relative to the fluid.
