Claim 14:
15. A system for determining volume of fluid in a fluid container, the system comprising:
a fluid container capable of storing a volume of fluid;
at least one differential pressure sensor positioned within the fluid container, the differential pressure sensor being configured for measuring pressure of fluid surrounding the differential pressure sensor in the container;
at least one vent line operably connected to the at least one differential pressure sensor, the at least one vent line having a single end through which air may flow and atmospheric pressure may be communicated to the at least one differential pressure sensor, the at least one differential pressure sensor being further configured for generating an output signal indicative of the differential pressure between the detected fluid pressure and the communicated atmospheric pressure; and
at least one processor constituting a part of the at least one differential pressure sensor and operable for determining the volume of fluid in the container as a function of the generated output signal indicative of the differential pressures applied to the sensor.
