Claim 0:
1. A system for determining volume of fluid in at least one tank, the system comprising:
at least one tank mounted on a vehicle, the at least one tank being capable of storing a volume of fluid;
at least one differential pressure sensor positioned within the at least one tank, and submersed in fluid when fluid is in the at least one tank, the at least one sensor being configured for measuring pressure of fluid proximate to the bottom of the at least one tank;
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 sensor, the at least one sensor being further configured for generating a differential pressure output signal indicative of the fluid pressure less the atmospheric pressure; and
at least one processor coupled to the at least one differential pressure sensor and operable for determining the volume of fluid from a received indication of the differential pressure output signal.
