You can use a ui-control node. That will send a message every time you open the page, switch tabs, refresh etc. You can use that to clear the data on the tab.

Have you looked at the help pane for the control node?

Have you dropped one onto a flow and fed the output to a debug node set to show Complete Message? and looked to see what comes out when you refresh the dashboard browser page?
