This patent describes a submersible sensor adapted to be immersed in a submerging liquid within a containing means for sensing electrically different conductive mediums in the liquid. The submerging liquid has a minimum selected level and a maximum selected level in the containing means, comprising first and second electrodes spaced from each other with opposed ends to define a sensing gap, means in the sensing gap between the electrodes to vary the conductivity of the gap with the conductivity of the mediums in the gap, a flow control enclosure secured defining a chamber about the opposed ends of the electrodes and the gap. The flow control enclosure having mounting means for attachment to the containing means and the flow control enclosure includes at least one first opening means located to establish flow of the submerging liquid into the chamber at a rapid inflow rate to immerse the opposed ends and at least one second opening means constructed and arranged to establish the flow of the submerging liquid from the chamber at an outflow rate less than the flow rate of the first opening in response to movement of submerging liquid about the enclosure, and the first opening means being located to introduce liquid into the chamber with the liquid level substantially at the minimum selected level and below the maximum level to maintain flow into the first opening means and the liquid in the chamber flowing from the chamber through the second opening means with the submerging liquid substantially at the minimum level and below the minimum level.
