An electronic level having a horizontal and/or a vertical transducer, each of which exhibits an effective impedance that is a function of the deviation of that transducer from a reference plane. Preferably, each transducer is an electrolytic transducer formed of a container partially filled with electrolytic liquid. Depending upon the general horizontal or vertical orientation of the level, one or the other transducer is connected to a drive signal generating circuit which supplies an output drive signal of a magnitude that is a function of the impedance of that transducer. This output drive signal is applied to a display driver which, in turn, drives an array of visual indicators in accordance with the output signal magnitude.
