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.
