SureSite Level Indicator: Operating Principle

As liquid level rises, a magnet-equipped float within the SureSite unit inverts the magnetic flags in the external indicator to "color-side-out." The flags remain magnetically interlocked in a column until again inverted to "contrasting-side-out" by the float as liquid level falls. Liquid level is indicated by the junction of the "color" and "contrasting" portions of the column.
