In a previous blog post, we discussed the need for, and importance of, barometrically compensating your Levelogger data. Now we will discuss how to actually go about doing a barometric compensation. Here we will focus on our recommended method, which is by using a Barologger and the Levelogger Software Data Wizard. Continue Reading »
As you know, Leveloggers measure total or absolute pressure. When submerged, they record a combination of atmospheric pressure and water pressure above their sensor. Because the intent of using Leveloggers is to obtain fluctuations in water pressure only, their data must be compensated for atmospheric effects. In order to achieve this, atmospheric… Continue Reading »
Because the goal of Leveloggers is to provide fluctuations in water pressure only, their data must be compensated for barometric effects. In order to achieve this, barometric pressure must be subtracted from the Levelogger readings to give actual water level data. Continue Reading »
Automatic Barometric Compensation Submersed Leveloggers measure total or absolute pressure (water column equivalent + barometric pressure). In order to accurately determine the true changes in water level only, barometric pressure fluctuations must be taken into account. The simplest method to accomplish this is by the use of a Barologger suspended above high water level in one well… Continue Reading »
