1. Actual vertical distance between the area velocity sensor and the liquid surface
2. Maximum non-linearity , hysteresis, and temperature error from actual liquid level
3. In water with a uniform velocity profile and a speed of sound of 1480 m/s (4850 ft./s)
4. The serial tag of the AV2150EX sensor contains important X marking, indicating special safety conditions that must
be observed. See Important Information Regarding "X" Marking on page 2-29 for more information.
