Abstract
A fluid flow control system (20) comprises a pumping assembly (22) for pumping a fluid (23) through an orifice (30), and a pressure measuring assembly (32) for measuring, and providing information on, the change in pressure across the orifice (30). The fluid flow control system (20) also includes a controller (36, 38) to adjust the pump assembly (22) in accordance with the aforesaid information and vary the rate of flow of the pumped fluid.
Claims40
A fluid flow control system comprising a pumping assembly for pumping a fluid through an orifice, a pressure measuring assembly for measuring and providing information on the change in pressure across the orifice, and a controller for processing the aforesaid information to adjust the pump assembly in accordance with the aforesaid information and vary the rate of flow of the pumped fluid.
A method of controlling fluid flow, the said method comprising pumping a fluid through an orifice, measuring the pressure drop of the fluid across the orifice, providing information on the change in pressure across the orifice, processing the aforesaid information and adjusting the pumping assembly in accordance with the processed information to vary the rate of flow of the pump fluid.
