ABSTRACT:
A sensor can detect the difference in potential between itself and the fluid into which it is immersed, a signal generated by the probe representing this difference in potential. This signal is used to activate an oscillator circuit. By varying the conditions at which current in the oscillator circuit begins to oscillate, various liquids can be detected and identified.
