* Water level accuracy: Accurate measurement of reference water level, known water density, accurate barometric compensation data and stable ambient temperature.
** Gross pressure accuracy: The absolute accuracy of the pressure sensor includes all errors due to drift, temperature and hysteresis.
*** Temperature variations: Leave the pressure sensor immersed for 20 minutes for complete thermal compensation. The maximum error due to rapid thermal variations is about 0.5%.
