This article examines the linearization of a nonlinear transfer characteristic in a two-component sensor, with the potentiometric level meter serving as a case study. The conducted analysis employs a method of interpolation involving two interrelated variables: the liquid level readings are contingent upon both the liquid level and the liquid conductivity, while the liquid conductivity readings are influenced by both the liquid conductivity and the liquid level. The objective of the current paper is to identify a mathematical approach that enhances the precision of the measurement. A methodology for linearizing the nonlinear transfer characteristic of a conductivity level meter was established through the integration of two conversion correction tables and piecewise quadratic interpolation with iteration in the form of a table algorithm. This approach resulted in a reduction in the measurement error compared to the interpolation methods without iteration.
