What is the difference between a Levelogger and Barologger?
Leveloggers record changes in absolute pressure (water column pressure + barometric pressure) with time. The Barologger functions and communicates similarly to the Levelogger, but is used above the water level to record ambient barometric pressure in order to barometrically correct data recorded by the Leveloggers. Typically one Barologger can cover a radius of 30 km (20 miles) and/or every 300 m (1000 ft) elevation change.
How do I select the correct pressure range of Levelogger for my application?
The choice of pressure range largely depends on the accuracy of the water level required and the desired submergence depth. The selection, however, should be based on the maximum anticipated water level fluctuation.
Example: The Levelogger 5 M5 is designed for 5 meters or 15 feet submergence and provides a typical water level accuracy of ±3 mm (0.01 ft). This instrument is ideally suited for surface water and shallow groundwater applications, where precise water level measurements are essential.
If, however, the anticipated water level fluctuation will be greater than the designed range, then the next available range should be chosen for that application.
Example: 10 meters (30 feet) water level fluctuation is expected. To protect from possible over-ranging, the next available pressure range instrument (Levelogger 5 M20) should be selected.
How do I know that I'm using the most current version of software and firmware?
The most current Levelogger software and firmware versions are available on the Solinst website Downloads page. You can check from time-to-time to see if you have the most current version, or by registering your software when you download it, you will receive automatic email messages notifying you when new software or firmware becomes available.
In addition, when using Levelogger Software Version (4.0.1 and up) on a computer with an Internet connection, automatic notifications will be provided when new software and firmware releases are available. Clicking on the notification message will take you right to the software/firmware download page.
Do I have to pay for software and firmware?
No, all current software and firmware versions are available to download free from the Solinst website. If you register your software when you download it, you will receive automatic notices when new software or firmware has been released.
Levelogger software comes equipped with a "Firmware Upgrade Utility". As new firmware versions become available they can be downloaded free from the Solinst website and uploaded to your Levelogger using the Utility. Ensure the software is the latest version, as it contains the most recent Firmware Upgrade Utility.
