Abstract: Apparatus features a signal processor or processing module configured to respond to signaling containing information about a set point and a speed related to one or more pumps in a pump system, e.g., including a variable speed multiple pump booster system, operating at a substantially constant discharge pressure; and determine an adjustment to the set point to compensate for system friction loss and maintain the substantially constant discharge pressure of the variable speed multiple pump booster system for flow variation, based at least partly on the signaling received. The signal processor or processing module 10a provides corresponding signaling containing information to control the one or more pumps in the variable speed multiple pump booster system.
