New Versatile Submersible Water Level Transmitter from Solinst
Solinst is excited to introduce the Solinst Model 301 Water Level Temperature Sensor, providing the option of highly accurate water level transmission using multiple protocols, including MODBUS and SDI-12.
This compact, all-in-one submersible hydrostatic level transmitter provides continuous water level and temperature readings using absolute (non-vented) or gauged (vented) pressure sensors. Accuracy is 0.05% FS with six pressure ranges (5–200 m) and communication cable assemblies available in lengths up to 300 metres.
Sensors are enclosed in a 316L stainless steel housing with double o-ring seals to prevent leaks, and a Faraday cage design to protect against power surges and lightning. A 1/4" NPTM threaded connection provides the option of attaching to pipes/conduits.
With the fastest output rate on the market at 1 second, the Water Level Temperature Sensor is easy to integrate into existing monitoring systems, e.g., SCADA or PLC. Measure hydrostatic liquid levels long-term in both industrial and environmental applications.

Levelogger Data Critical for Water and Leachate Management at a Queensland Landfill
After a significant rainfall event at a landfill in southeast Queensland, Australia, it was determined that more detailed data was required in order to properly assess groundwater trends and responses to future events. Solinst Levelogger 5 water level dataloggers were installed across the groundwater monitoring network. Based on the high quality data and understanding gained from the Leveloggers, more loggers were installed in the sites surface water and leachate level monitoring systems. Overall, Levelogger 5 dataloggers have allowed for more detailed monitoring and analysis of groundwater, surface water, and leachate.

Building Knowledge to Ensure Climate Change Readiness
Detailed water monitoring and planning are required to ensure that communities relying on surface water resources are protected from future climate change impacts. Significant weather and hydrologic events in the north Kootenay Lake area of British Columbia, Canada spurred citizens in the region to start taking an active role in preparing for a changing climate.
This community concern led to the establishment of the Kootenay Watershed Science (KWS) – a community-driven project that has taken the lead in understanding how climate change will impact the small and medium-sized watersheds in their region.

Water Level Data Helps to Understand the Effects of Climate Change on Alpine Lakes
The Canadian Rocky Mountain Parks are designated as UNESCO World Heritage Sites for their "exceptional natural beauty".
They are known for their scenic mountain peaks, meadows, canyons, caves, hot springs, and glaciers. Their pristine alpine lakes also draw millions of visitors to the parks each year.
But as we hear so often…due to the effects of climate change, these spectacular alpine lakes may also be changing.
Janet Fischer and Mark Olson, professors in the Biology Department at Franklin & Marshall College in Lancaster, Pennsylvania, are leading a research project where Solinst Leveloggers are being used to monitor alpine lakes in Banff and Yoho National Parks to help study the effects of climate change.

Water Level Data Critical For Successful Coastal Wetland Restoration
Over 90 per cent of historical coastal wetlands in South Central California have been lost due to development — one such area is the former upper arms of the Devereux Slough. A huge restoration project is aiming to restore 100 acres of this land back to its natural state, including over 40 acres of wetland! See how The Cheadle Center for Biodiversity and Ecological Restoration at UCSB is using Levelogger data to track, monitor, and ultimately provide insight on the impacts and success of this major wetland restoration effort.
