ABSTRACT:
Systems and methods are disclosed for the automatic control of one or more pumping and compressing machines and of the related fluid network. The purpose of such systems and methods is to maintain only the required pressure just after a source or just before a user so as to reduce the compressing or pumping energy required; to divide the load within a group of one or more compressing or pumping machines so as to compress the fluid with reduced use of energy and improved pressure control; to improve protection of the turbo compressors when used in parallel from dangerous levels of operation.
