7 .1 Introduction
Run switching (also known as meter run staging or tube switching) is a function that controls
the flow of fluid across multiple streams in a station. It normally is meant to optimize the ac-

To use run switching, it must be turned on first, under the general section.
The main run switching parameters must then be set per stream that will be used with the func-
tion.
