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.

The new Biofoul Screen is designed to fit onto the sensor end of any Levelogger model. The natural anti-fouling characteristics of copper protects the sensors from build-up of unwanted microorganisms, plants, algae, or organisms such as barnacles or mussels, which could affect the reliability of the sensor readings.

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 »
Solinst has released new versions of the Model 101 P7 Water Level Meter and the Model 107 TLC Meter. Each Meter now features Solinst Laser-Marked Flat Tape. The new tape boasts many advantages. Continue Reading »
Attendees enjoyed the presentation by Steve Holysh and Rick Gerber of the Oak Ridges Moraine Coalition. They presented work being done for the Region’s unique groundwater management program. Rapid growth and expansion on the Moraine triggered the program into action about 20 years ago, to more fully understand the extent, quality and movement of the… Continue Reading »
