ABSTRACT:
A fluid level measuring system comprising a fluid level sensor is disclosed. The fluid level sensor may comprise a top or bottom mounted transducer and limited openings to enable accurate measurement of a fluid's depth while the fluid is moving. The fluid level measuring system may be calibrated without the use of calibration reflectors and may be used to retrofit prior art fluid level measuring systems. A control system may be used to control the fluid level sensor and interface the fluid level sensor to an external subsystem, such as a fuel gauge.
