Abstract
A method for controlling the supply flow through a compressed fluid system having a fluid compressor with a inlet valve, and a host system in signal receiving relation with a supply flow sensor and in signal transmitting relation with a compressor controller. The method includes the following steps: sensing the actual compressed fluid supply flow, sending a first signal representing the actual compressed fluid supply flow from the flow sensor to the host system, sending a second signal, with a current corresponding to the required predetermined required inlet vacuum, from the host system to the compressor controller, sensing the actual vacuum at the fluid compressor inlet, and comparing the actual vacuum at the fluid compressor inlet to a predetermined target vacuum required to produce the desired supply flow through the compressed fluid system, and if the predetermined target vacuum is greater than the actual vacuum, performing the additional step of closing the inlet valve until the actual vacuum is substantially equal to the predetermined target vacuum and if the predetermined target vacuum is less than the actual vacuum, performing the additional step of opening the inlet valve…
