Abstract
The present invention is directed to a system for determining a fluid level in a vessel. The system comprises a first differential pressure transducer, a second differential pressure transducer, a pressure delivery system, and a fluid passage. The first differential pressure transducer includes a first side and a second side. The first side is selectively in fluid communication with a portion of the vessel above the fluid level. The second differential pressure transducer includes a third side and a fourth side. The third side is selectively in fluid communication with a portion of the vessel below the fluid level. The fluid passage is in fluid communication with the second side of the first transducer, the fourth side of the second transducer, and the pressure delivery mechanism.
