Hermetically sealed reed switches are located in the switch stem at the desired measurement levels. The switches are actuated by magnets embedded in the floats as they rise and fall with the liquid level. The floats have a predetermined travel on the stem to ensure that the switches are held in the correct condition for its respective level.
