摘要： The invention described relates to an apparatus and method for measuring the concentration of a low molecular weight alcohol, in an aqueous liquid feed solution, comprising a first sensor including a hydrophilic capillary tube having an inner diameter, being disposed between two electrodes to form a first capacitor, a second sensor including a hydrophobic capillary tube having the same inner diameter as a capillary tube of the first sensor; said hydrophobic capillary tube having a hydrophobic coating on the inner diameter, being disposed between two electrodes to form a second capacitor, wherein the first hydrophilic and second hydrophobic sensors are dipped to the same depth in the aqueous solution to measure the solution concentration, means for measuring the capacitance of the two capacitors, and control means including a control circuit driven by a computer, wherein the difference in capacitance between the two capacitors is a measure of the concentration of the solution, independent of the depth of dipping of the two capacitors in the aqueous solution. In another embodiment, a single hydrophilic sensor is employed.
