Accurate Barometric Compensation
Leveloggers measure absolute pressure (water pressure + atmospheric pressure) expressed in feet, meters or centimeters of water column.

Accurate Barometric Compensation Leveloggers measure absolute pressure (water pressure + atmospheric pressure) expressed in feet, meters or centimeters of water column. |
|
| Description |
The most accurate method of obtaining changes in water level is to compensate for atmospheric pressure fluctuations using a Barologger. This avoids any time lag in the compensation calculation and any errors introduced due to moisture buildup, kinking or damage to vented cable. The new Barologger EDGE uses algorithms based on air rather than water pressure, which gives superior accuracy. The recorded barometric information can also be very useful to help determine barometric lag and/or barometric efficiency of the monitored aquifer. The Data Compensation Wizard in the Levelogger software greatly simplifies the barometric adjustment of the water level measurements by using the synchronized data from one on-site Barologger with all the Leveloggers. The overall results give more reliable, highly accurate level data than that obtained when using high maintenance and expensive vented cable. |
| Helpful Utilities |
The ‘Self-Test Diagnostic Utility’ can be used in case of an unexpected problem. It checks the functioning of the program, calibration, backup and logging memories, the pressure transducer, temperature sensor and battery voltage, as well as enabling a complete Memory Dump, if required. A Firmware Upgrade will be available from time to time, to allow upgrading of the Levelogger EDGE, as new features are added. |
