Details
Absolute pressure (water pressure + atmospheric pressure) is measured by the Levelogger 5 and is expressed in meters, centimeters, feet, psi, kPa or mBar. To obtain changes in water level accurately, atmospheric pressure fluctuations need to be compensated for using a Barologger 555 which avoids time lag in the compensation.
The Barologger is set above high water level in one location on site. A single Barologger can be used to compensate for atmospheric pressure for all Leveloggers in a 30 km (20 mile) radius and/or with every 300 m (1000 ft) change in elevation.
Compensated data files are automatically produced by the Levelogger Software Data Compensation Wizard using the synchronized data files from the Barologger and Leveloggers on site.
Pressure algorithms, based on air rather than water pressure, are used by the Barologger 5 providing superior accuracy. The recorded barometric information is also useful to determine barometric lag and/or barometric efficiency of the monitored aquifer.
Atmospheric pressure is recorded by the Barologger 5 in psi, kPa or mBar. When compensating data from the Levelogger 5, Gold or Junior, Levelogger Software Version 4 can recognize the type of Levelogger and compensate using the same units found in the data file (Levelogger Gold and Junior measure in centimeters, meters or feet). This makes the Barologger 5 backwards compatible.
