Method for quantitative measurement of fluid conductivity, providing more accurate measurements of its dielectric constant, for use in measuring the composition of alcohol water mixtures used in damping in offset printing

摘要

Method in which the voltage difference between the output voltage of a high frequency generator and the voltage of a measurement circuit that is detachably connected to the generator is measured. The voltage difference is dependent on the circuit capacitance and inductance and the output difference voltage is a measure for the circuit capacitance. Additionally measurement circuit damping is measured and used for the quantitative determination of fluid properties, especially the conductivity.
