A capacitive sensor is employed to measure the dielectric constant of miscible liquids, and thereby determine the relative concentration of the two liquids. Further, a feedback circuit may be provided to change the operation of the system in accordance with the relative concentration of the liquids. Further, circuit arrangements may be provided to adjust the sensitivity and offset of the electrical circuit included in the system to match the output of the sensor with the dielectric constants being measured.
