  • Ultra sensitive liquid level detector and method
    Patent number: 4329875
    Abstract: A highly sensitive liquid level detection system. It employs a piezoelectric transducer that has a natural frequency of vibration which effectively varies depending upon the amount that the transducer is immersed in a liquid. An emf is applied to the transducer to cause it to vibrate at the effective natural frequency, and the exact frequency is counted which count indicates the amount of immersion with a high degree of accuracy. A printer may be employed to periodically record the frequency count.
