A sensing device (10) is provided for sensing whether an electrically- conductive fluid (14) has reached a predetermined level within a container (12). In this device (10), a first electrode (22) is electrically connected to a source (20) and a second electrode (24) is electrically connected to ground. When the electrode gap (26) is filled with the fluid (14), the sensing circuitry causes the electrodes (22, 24) to switch roles as the anode depending upon whether a positive voltage pulse or negative voltage pulse is being received from the source (20).
