NexSens AccuStage water level sensors are simple and durable
For monitoring water level and wave height, NexSens AccuStage water level sensors are durable, easy to use, and require little maintenance. Users can choose between titanium or stainless steel constructions. 
 
The sensors work by transducing water pressure into a millivolt charge, which can then be interpreted by data loggers as water level or wave height, depending on user needs. Two models of the sensor, vented or absolute, provide easy interfacing with NexSens iSIC or submersible data loggers. The sensors can communicate through Modbus RS485 or analog. 
 
“They’re used in streams and lakes most commonly,” said Kevin Stevens, product manager. “Many customers use deployment pipes, just to keep it more secure, and some also use conduit to protect the cable.

Dayton, OH, March 20, 2009 — New from NexSens Technology, the SDL500 is a rugged, self-powered remote data logging system housed in an impact-resistant, submersible PVC enclosure. The underwater data logger is designed for deploying environmental sensors in streams, rivers, wetlands, coastal waters, sewers , and culverts without fear of accidental flooding. 
 
 Common sensor connections include multi-parameter sondes, water quality sensors, temperature strings, Doppler velocity meters, water level sensors, rain gauges, and weather stations. The SDL500 can be powered autonomously by eight D-cell alkaline batteries. Optional solar power kits provide long-term continuous operation and solar charging.

The prairies of Saskatchewan can be described as one of the least water-secure parts of Canada, making water quality monitoring essential for informed resource management in a region already facing water insecurity. While natural physical properties worsen some of the poor water quality conditions in the region, others are connected to land use. 
 
Having grown up spending summers on the shores of Lake Huron, Helen Baulch, an associate professor at the School of Environment and Sustainability at the University of Saskatchewan , has always been dedicated to the protection of water resources. 
 
Looking back fondly at her childhood playing along the shore, Baulch also recalls the invasion of quagga mussels during her teenage years and watching the lake change as a result.
