In practice, with only two electrodes, ripples on the In practice, with only two electrodes, ripples on the surface of the liquid cause the Controller to jump and surface of the liquid cause the Controller to jump and start, shortening pump (and other equipment) life. This start, shortening pump (and other equipment) life. This problem can be solved by adding another electrode to problem can be solved by adding another electrode to form a self-holding circuit. The additional electrode, E2, form a self-holding circuit. The additional electrode, E2, is connected in parallel with E1, as shownis connected in parallel with E1, as shown
