Abstract

A method for measuring a permittivity (ε) of a material () includes following steps. A sensing rod () of a material level sensor () inserts into a tank (). The material level sensor () proceeds with a material level measurement of the material () to obtain a first feature value. The material level sensor () is vertically moved with a vertical distance (Hair). The material level sensor () proceeds with the material level measurement to obtain a second feature value, and subtracts the first feature value by the second feature value to obtain a feature value variation, and calculates the feature value variation to obtain the permittivity (ε) of the material ().
