Abstract: PROBLEM TO BE SOLVED: To provide a differential pressure gauge which an operator inputs onboard tank dimensions, tank orientation, stratification coefficient and the type of liquid stored within the tank. SOLUTION: A differential pressure sensor supplies a signal corresponding to a differential pressure. A pressure sensor supplies a signal corresponding to the head pressure. The gauge uses the information supplied by an operator, combined with stored formulas and liquid characteristics, to perform real-time liquid volume computations. The liquid volume man be displayed on the gauge itself or may be transmitted via telemetry to an external device.

Abstract: A differential pressure gauge for a cryogenic storage tank provides onboard entry, by an operator, of tank dimensions, tank orientation stratification coefficient, and the type of liquid stored within the tank. A differential pressure sensor supplies a signal corresponding to a differenti al pressure. A pressure sensor supplies a signal corresponding to the head pressure. The gauge uses the information supplied by an operator, combined with stored formulas and liquid characteristics, to perform real-time liquid volume computations. The liquid volume may be displayed on the gauge itself or may be transmitted via telemetry to an external device.
