1. A system for determining volume of fluid in at least one tank, the system comprising:
at least one tank 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 differential pressure sensor being configured for measuring pressure of fluid proximate to the position of the sensor in the at least one tank and for adjusting a measurement of fluid pressure by atmospheric pressure; and
at least one processor in communication with the at least one differential pressure sensor and operable for generating fluid volume output signals based on detected tank fluid pressure adjusted by atmospheric pressure.
