Over Filling/Emptying Tanks

When using the predefined subroutines to fill, empty, or transfer from one tank to another, you may accidentally attempt to over fill or over empty a tank. To prevent these situations, you have the option to terminate the fill/empty subroutine or suspend further filling/emptying until the tank reaches a resume level. If you terminate the subroutine, ProModel temporarily stores the un-filled or un-emptied quantity for immediate access in the global variable, Tank_QtyLeft.
