Sažetak
This paper presents a simple low-cost measurement method for determination of a conductive liquid layer thickness with an unknown conductivity, by means of measuring the resistance between pairs of electrodes arranged in a planar multielectrode configuration. The measurement method tolerates unknown layer conductivity variations over a few orders of magnitude, without a significant impact on the measured layer thickness uncertainty. The accuracy of thickness determination was confirmed by an experiment and it is better than 300 um in the range of 2 to 10 mm, for the electrode arrangement optimized for the target thickness range. The applications of the proposed method are numerous, ranging from the industrial quality control, process monitoring, environmental sensing etc.
