In this article design and operation of a parallel-plate capacitive sensor based on the dielectric
capacitance and conductance change of the gap medium is reported. The designed system was used to
determine characteristics of different water liquids as a result of the capacitance variations. The air gap
capacitance is measured and then by filling the gap with a liquid the capacitance is monitored for different
liquids. Proposed sensor is used for the distilled, tap, boiled, and salt water measurements and the capacitance
results are compared. A big difference about 45.5 :F in capacitance values for the salt and distilled water shows
a high sensitivity, which can be used to recognize different water liquids. The experimental results are
promising for water liquids and verify the successful operation of such a device as a liquid sensor, a useful
method for checking the electrical quality of the water that is required for different applications.
Key words: Capacitance, conductivity, permittivity change, sensor, water liquids, ,
