The Environmental Monitoring Catalog of Sensors, Samplers and Systems

Our catalog includes the most complete line of environmental monitoring sensors, samplers and systems for measuring water and weather. Our instrumentation has a strong reputation for durability, ease of use and the most common, easiest to set up, interface with your PC.


Water Level Logger (WL14) Groundwater * Surface Water * Stormwater * Sewers


  • Low Power / Internal Battery
  • Logs 6000 Readings
  • 12 Bit Resolution (0.003')
  • 0.2% Accuracy
  • EZ-PC Software (Included)
  • Temperature and Barometric Pressure Compensation

The WL14 includes a datalogger with water level sensor for remote monitoring and recording of water level data. This highly reliable and accurate water level logger records 6000 readings and it is programmable from one reading per minute to one reading per hour. Range of 0 -14' water level is standard. (See optional ranges below). A 25' cable is provided with optional cable lengths to 500'.

The Global WL14 Water Level Logger is housed in a weatherproof cylindrical enclosure. It is easily adapted with standard hardware for well-head mounting or other installations. The internal 9 VDC battery powers the logger and sensor for one year. EZ-PC software allows upload of data to standard spreadsheets on any PC computer.
