Abstract
A surge control system and method include a valve assembly located along a fluid conduit downstream of one or more compressors in a flow circuit, and configured to receive a fluid stream from the one or more compressors. The valve assembly includes a valve body, a pitot tube integrated onto the valve body, and a pressure sensor device operably connected to the pitot tube. A controller of the surge control system receives pressure measurements generated by the pressure sensor device. The pressure measurements represent pressure in the pitot tube over time. The controller analyzes at least one of (i) the pressure measurements or (ii) flow velocity values derived from the pressure measurements, and detects a surge condition in the flow circuit based on oscillations in the at least one of the pressure measurements or the flow velocity values.
