Van Essen TD-Diver Water Level Loggers

Overview
The Van Essen TD-Diver is a reliable instrument for autonomous measuring and recording of groundwater level and temperature. Its internal memory of 72,000 measurements per parameter provides sufficient capacity to perform nearly one measurement every hour for 8 years. A new backup memory feature enhances data integrity. For each measurement, the Diver registers the date and time, groundwater level, and temperature.

Precision
The Van Essen TD-Diver is an easy-to-use datalogger featuring state-of-the-art electronics and a robust high-precision pressure sensor for long-term accuracy. The absolute pressure sensor requires minimal maintenance and re-calibration.

Applications

  • Monitor potable water recharge areas for water supply
  • Monitor tailing ponds, dewatering activities and water supply levels of mines
  • General site investigations for construction
  • Contaminant plume monitoring on spill sites, remediation sites, chemical storage facilities
  • Landfill sites and hazardous waste storage sites
Questions & Answers
Can this logger read water level accurately in a 1" well?
The Van Essen TD-Diver measures about 0.9 in and is good for deplyoment in 2" and 4" wells. However, if the inner diameter of the well is larger than 22cm, then the logger can be deployed without any interferences.

Combating Water Insecurity in Saskatchewan with Real-Time Data

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.
