4.2 Barometric Compensation

Levelogger 5 dataloggers use an absolute pressure sensor, therefore, detect total pressure above the sensor (water plus barometric pressure).

To eliminate barometric pressure and display water level only, select Next after taking a reading (Section 4.1). Select to turn barometric compensation on. The SRU contains an internal barometer that barometrically compensates the level readings. The barometer reading will be displayed on this screen.

LevelVent 5 and AquaVent 5 vented water level dataloggers use gauged pressure sensors, therefore, barometric effects are already eliminated from the level reading through the vented cable.

Barometric compensation can be turned off in the same screen.
