Notices

: * Water Level Accuracy: With accurate reference water level measurement, known water density, and a stable temperature environment.
: ** Raw Pressure Accuracy: Absolute pressure sensor accuracy includes all sensor drift, temperature, and hysteresis-induced errors.
: *** Changes in Temperature: Allow 20 minutes in water to achieve full temperature compensation of the pressure sensor. There can be up to 0.5% of additional error due to rapid temperature changes.
: Measurement accuracy also depends on temperature response time.
