Abstract: A fluid level measurement system includes a first pressure sensor disposed inside a fluid tank at a first elevation relative to a height axis of the fluid tank, and a second pressure sensor disposed inside the fluid tank at a second elevation relative to the height axis of the fluid tank, the second elevation different from the first elevation. The first pressure sensor and the second pressure sensor are configured to provide a signal indicative of a sensed pressure, and fluid height is calculated from the difference in sensed pressure between the first and second pressure sensors relative to the sensed pressure of either the first or the second pressure sensor.
