Abstract
A system and method for continuous level sensing is disclosed. The system employs a continuous level sensing strain gauge measuring a weight of an aircraft waste tank, a lower and upper point level sensors to signal the system as the liquid level reaches each sensor, and a flush counter to correlate with the CLS and the PLS to determine an average flush volume (AFV). Once the AFV is known and updated, the system determines a weighted waste tank level based on a weighted addition of the flush count and the quantity as measured by the CLS. As the aircraft tank reaches a predetermined value, the system alerts a crewmember to the status.
