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 »
The Environmental Protection of International River Basins is a EU (European Union) funded project with the overall aim of improving water quality in the trans-boundary river basins of the wider Black Sea region and Belarus. An objective of the project is to improve the availability and quality of water data in the region, including groundwater… Continue Reading »
A number of Leveloggers were deployed at this restoration site along the Hackensack River as a permit requirement to document tidal hydrology. Over the many months that the Leveloggers were deployed, heavy biofouling was observed on the Leveloggers. 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 »
Have you noticed a difference in raw water level (pressure) readings when comparing data recorded by the latest Levelogger Edge line versus previous models? Find out why. Continue Reading »
The program includes the use of the Solinst LTC Levelogger Junior to monitor changes in water level, temperature, and conductivity in rivers and streams. Conductivity readings provide a general indication of the water quality, while the water level and temperature readings may be used to provide background information when any spikes or significant changes in conductivity readings are noticed.

Vernal wetlands are temporary pools of water that fluctuate seasonally with complex hydrological processes. They receive inputs from precipitation, runoff, and subsurface flow, and are influenced by geology, soil, and climate. This creates a unique habitat for diverse flora, amphibians and insects, including some threatened and endangered species. Continue Reading »
James Sullivan, Staff Environmental Scientist with GeoTrans Inc., has been very satisfied with the use of Solinst instruments in a variety of groundwater monitoring projects: “The reliability of Solinst Water Level Meters is second to none when it comes to accuracy, precision and durability. In the groundwater field I have utilized several different types of water level… Continue Reading »
Over the last two years, researchers in the Department of Civil and Environmental Engineering at the University of Louisville have been conducting an extensive assessment on a stream in Oldham County, Kentucky. The stream, which can be classified as “headwater”, has a drainage area of about 2.8 square miles (7.2 square kilometers) at the upstream… 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 »
