A bin or tank level monitoring system uses a capacitance-sensing device with at least one electrode vertically extending from near the top to near the bottom of the tank. Changes in the level of the material held in the tank causes the effective dielectric constant of the electrical capacitance between the electrode and for example, an adjacent conductive tank wall, to change continuously and proportionately. The change in the dielectric constant changes the actual capacitance between the electrode and the tank wall. Circuitry forming part of the system can measure this change in capacitance and use the measurement to provide an accurate indication of the level of material in the tank. A variety of configurations of the electrode or electrodes allows level detection for both conductive and non-conductive tanks and for different types of materials held in the tanks.
