An apparatus for intended use in measuring, sensing, or detecting a characteristic of a fluid, such as a liquid food product, is disclosed. In an exemplary embodiment, the method includes creating a preset voltage level within the cell prior to a delayed write back in a destructive read architecture, which preset voltage level has a value between a logic 0 voltage level and a logic 1 voltage level. The edge strip is provided with a receptacle at either end of the channel, and each receptacle can accommodate an end portion of an edge strip mounted on a side edge of the cathode.
