Abstract
A new technique of calibrating a parallel-wire depth probe is presente d. The technique allows the effects of electric conductivity of liquid s to be compensated. The advantage of the probe lies in its simple AC circuitry employed which consists of only a variable resistor together with one AC input and an AC output. The compensation technique employ s a two-staging compensation method that allows only one calibration c urve to be used for measuring the depth of various liquids with differ ent electric conductivity values.
