  • Differential pressure sensor for fuel delivery systems
    Patent number: 7765978
    Abstract: A differential pressure sensor apparatus for use in a fuel delivery system measures the differential pressure of the fuel between a point immediately upstream and a point immediately downstream of a fuel monitor element. The differential pressure sensor apparatus uses an electronic transducer to monitor differential pressure and may be used with interlocks to shutdown fuel delivery if the measured value of the differential pressure is above a predetermined threshold value and to notify an operator of the fuel delivery system of such an increase in the differential pressure.

  • Scaled quadrature pulse signal generator
    Patent number: 6535830
    Abstract: A scaled quadrature pulse output signal is generated for representing direction and volume in predetermined increments of the flow of a liquid or a gas through a meter. An unscaled pulse signal is received from a meter. A scaling factor is applied to each unscaled pulse signal for accurately representing an increment of volume. The increments are sequentially added or subtracted to/from one another (depending upon flow direction) and a scaled quadrature output signal is provided for indicating the direction of flow and the volume of flow in predetermined increments.
