Solinst Levelogger 2" Well Cap Assembly

The Solinst Levelogger Well Cap Assembly is designed to fit 2" wells, and provides options for installing Leveloggers with wireline, Kevlar rope, or using a Direct Read Cable.


  • Simultaneously supports both Levelogger and Barologger
  • Cap is secured with twist lock and accommodates 3/8" (9.5mm) shackle diameter lock
  • Well cap is vented to allow for the equalization of barometric pressure in the well

The Solinst Model 3001 Well Cap Assembly for Leveloggers is designed to fit 2" wells (or 4" wells with Reducer), and provides options for installing Leveloggers with wireline, Kevlar rope, or using a Direct Read Cable. The well cap base provides a tight friction fit onto the well casing and is secured to the base with a twist lock. For further security, a 3/8 (9.5mm) shackle diameter lock can be used. The Well Cap is also vented to allow for the equalization of barometric pressure in the well.

When installing Leveloggers using a Stainless Steel wireline or Kevlar rope suspension, the water level dataloggers are securely supported when tied off to the eyebolt included on the underside of the well cap insert. When installing Leveloggers using a Direct Read Cable, the cable simply fits inside the convenient well cap insert hole, when the red dust cap is removed. For Levelogger installations where a Barologger is to be installed in the same well, the well cap supports up to two Direct Read Cables. Even with the two Direct Read Cables installed, there is still an access hole available for manual water level measurements or groundwater sampling, without disturbing the down-hole Leveloggers.

Questions & Answers
Will the Solinst 2” vented well cap allow for a deployed Levelogger to obtain accurate water level readings without the need for separate barometric compensation data?
The vented cap assembly will allow for atmospheric pressure stabilization within the well, however, the deployed Leveloggers will also need barometric pressure data to correct the readings for barometrically-compensated, water level data. More information can be found on page 16 of the manual:

Applied Research and Innovative Solutions: Creating CHNGES at Western Kentucky University

Long-standing environmental monitoring programs have the power to support a large number of research initiatives and policy changes—however, actually starting these networks can prove challenging. Not only is starting the program difficult, but keeping things operational for decades to come has also been challenging for environmental professionals hoping to make an impact with applied research. Jason Polk, Professor of Environmental Geoscience and Director of the Center for Human GeoEnvironmental Studies (CHNGES) at Western Kentucky University, is all too familiar with this process.

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.

Seametrics Turbo Turbidity Logger: Boost your Turbidity Monitoring

The Seametrics Turbo Turbidity Logger is a self-cleaning turbidity sensor capable of internally logging over 260,000 data records. The sensor enables researchers, compliance officers, and contractors to monitor turbidity in various applications, from construction and dredging sites to wastewater effluent.  Due to its narrow width, this device can be deployed in a range of areas, from small well spaces to rivers and streams. The stainless steel housing and built-in wiper allow the sensor to withstand long-term deployments and reduce the need for maintenance trips.  The logger accurately records temperature and turbidity up to a depth of 50 meters.
