1. A fluid flow circuit comprising:
- a fluid transfer device;
a pressure differential measurement device to measure the pressure differential across the fluid transfer device;
a power monitoring device to measure the power of the fluid transfer device; and
a controller in communication with the pressure differential measurement device and the power monitoring device, where said controller is programmed with software commands to automatically sample data reflecting the power and the pressure differential of the fluid transfer device and to automatically maintain a substantially constant fluid flow through the fluid transfer device based on the power and the pressure differential of the fluid transfer device.

Abstract
A flow control scheme for use with a flow circuit, including a fluid transfer device such as a pump or a compressor. The flow control scheme monitors the power and pressure differential of the fluid transfer device. The flow control scheme is capable of maintaining the flow of the fluid transfer device at a baseline value in response to varying operational conditions within the flow circuit.

6. A method of maintaining a constant flow of fluid within a fluid flow circuit comprising the steps of:
-
installing a fluid transfer device within a fluid flow circuit;
establishing a baseline flow for the fluid transfer device;
monitoring the pressure differential across the fluid transfer device;
monitoring the power provided to the fluid transfer device; and
adjusting the power provided to the fluid transfer device to maintain a flow through the fluid transfer device that is approximately equal to the baseline flow. - View Dependent Claims (7, 8, 9, 10, 11, 12)
