Flow compensated pressure control system

摘要

A control system is provided for monitoring and regulating fluid pressure at a remote and/or potentially hazardous location along the length of a fluid flow conduit, without requiring a pressure sensor device at the remote site. The control system comprises a controller responsive to fluid pressure and flow rate readings taken at a convenient and/or safe location along the length of the flow conduit, to derive fluid pressure at the remote site. The controller provides a display of the derived pressure and/or operates a control valve at the safe site to regulate the pressure at the remote site.
