Abstract
Control apparatus and method for controlling the flow of fluid across a valve includes a differential pressure measurement across the valve and a flow meter for measuring the flow, and the information from the differential pressure and from the flow meter is compared to predetermined parameters, and in response to the comparison, the valve is modulated to provide the desired flow.
