Flow variance is the actual flow compared to the expected flow. Both above and below expected flow conditions can be detected and then acted upon.

1.  On the main FlowStation App page, click the FlowStation where the mainline that you want to work with is assigned. The slide-out pane displays.

2.  Scroll down to the section where the mainline that you want to work with is shown. If necessary, click the header rows to expand the sections.

3.  Click the mainline that you want to work with. The Mainline information pane displays.

4.  Click Edit in the lower-right corner. The mainline details are available for editing.

5.  If necessary, click the Flow Management header to expand the section.

6.  In the Limit field of the Flow Variance row, click the up or down arrow to set the percentage for the allowable variance.

7.  If you want zones (valves) assigned to this mainline to be stopped and corresponding master valves (MVs) shut off when the flow rate exceeds the limit, click in the Shutdown field to display a check mark. If you do not want excessive flow to shut down the system, click in the Shutdown field to remove the check mark.

8.  Click Save in the lower-right corner.
