Dual Tube Switching for SCADAPack 4203 and Realflo

Metering stations are used to automate the flow measurement when fluctuations in pressure are expected because of production changes upstream.

The application described in this paper is a dual tube metering station. Run switching between the two gas flow runs is automated by a C Application for the SCADAPack 4203 gas flow computer and configured using a custom view within the Realflo software from Schneider Electric. A link is provided at the end of this paper to download the C application and Realflo sample project.
