Abstract
A fluid delivery and control system is provided for a fluid delivery line having elastic components. The system includes a pressure sensor, an electronically controlled valve, processing circuitry, and computer program code logic. The pressure sensor is operative to detect fluid pressure within a fluid delivery line. The electronically controlled valve includes an adjustable flow regulating aperture disposed in the line, interposed along a linear flow axis, and operative to regulate fluid flow through the line. The processing circuitry communicates with the pressure sensor and the electronically controlled valve. The computer program code logic is executed by the processing circuitry and is configured to generate an output signal. The output signal comprises an operating parameter of at least one of the pressure sensor and the electronically controlled valve to adjust flow capacity of the flow regulating aperture of the valve to dissipate pressure oscillations within the fluid delivery line. A method is also provided.
