Abstract
A flow management system for extracorporeal blood treatment application helps to ensure proper balance of incoming and outgoing fluids by precise balancing of relatively small balance chambers. The invention employs combinations of features that help to ensure accuracy including underfilling of the waste flow side of a fixed volume chamber and mechanical connections to synchronize valves and pumps.
