  • Liquid gaging system multiplexing
    Patent number: 4451894
    Abstract: A liquid gaging system comprising a plurality of sensors, each sensor providing a liquid measurement signal relating to a liquid depth at a particular location in a tank. The invention also comprises apparatus for selectively monitoring individual sensors one at a time. The apparatus for selectively monitoring is connected to the sensors.
    Type: Grant

  • Liquid gaging system contamination monitor
    Patent number: 4363239
    Abstract: The present invention is part of a liquid gaging system and comprises an apparatus for monitoring a quadrature signal from a capacitor sensor. Included is a capacitive sensor for providing a liquid measurement signal related to a liquid in a tank, the liquid measurement signal comprising a capacitive signal and a quadrature signal. The invention also includes apparatus for monitoring the quadrature signal through null detection of the capacitive signal, the null detection being implemented through a rebalance approximation sequence. The apparatus for monitoring is connected to the sensor.

  • Liquid gaging system null balance circuitry
    Patent number: 4350039
    Abstract: Circuitry for nulling a signal from a capacitive sensor apparatus with a signal from a reference. The invention includes capacitive sensor apparatus for providing a liquid measurement signal. Also included is reference apparatus for selectively providing a series of reference signals having predetermined amplitudes, the reference apparatus having terminal apparatus for receiving rebalance approximation sequence control signals for selectively controlling the signal amplitudes. The invention further includes null detecting apparatus for detecting the presence of a null, the null detecting apparatus being connected to the capacitive sensor apparatus and the reference apparatus.
