ABSTRACT:
An apparatus for measuring the level, volume or rate of flow of an electrically conductive fluid, such as water, includes a reference conductor connected to a reference potential and a plurality of additional, vertically spaced conductors affixed to an insulating surface. The reference conductor is normally placed at the lowest point of the liquid container whereas the other conductors are positioned within the liquid container at various points above the reference conductor. When the level of the liquid is above the position of one or more of the additional conductors, the liquid effects an electrical conduction path between the conductors below the liqid level and the reference conductor and thus with the reference potential. The conductors are connected through a logic circuit to a plurality of display elements, which are selectively actuated to provide an indication of the level of the liquid corresponding to the uppermost conductor covered by the liquid and thereby connected to the reference potential.
