In a fluid flow control system a weight comparator compares the weight of fluid in a reservoir with a weight reference that is programmed to decrease at a desired rate. A fluid flow comparator compares the actual fluid flow rate with a programmed fluid flow rate and operates directly on a flow controller to control fluid flow in the system. The weight comparator operates indirectly on the flow controller by recurringly updating the programmed fluid flow rate so that flow is controlled on a current basis by the fluid flow comparator and on a long-term basis by the weight comparator.
