Global Water WL16 Level Loggers

  • Automatic barometric pressure compensation
  • Stores 81,000 readings
  • Free user-friendly software

The WL16 Water Level Logger is a datalogger and submersible pressure transducer combination designed for remote monitoring and recording of water level or pressure data.

The water level logger can record over 81,000 readings and has 4 unique recording options, fast (10 samples per second), programmable interval (1 second to multiple years), logarithmic and exception. Multiple depth ranges are available from 3' to 500' of water level change. Optional cable lengths are available up to 500'.

The WL16 is housed in a weather-resistant cylindrical enclosure which slips inside a standard 2" pipe. A backup battery preserves stored data in the event the primary batteries fail. All WL16 loggers include a USB cable and Windows software allowing easy upload of data to a laptop, desktop or PDA for transfer to spreadsheet programs.

The WL16's vented submersible pressure transducer and electronics are fully encapsulated so moisture can never leak in through O-ring seals or work its way into the vent tube and cause drift or sensor failure.

The powerful and user-friendly Windows-based software features real-time readout, time interval and engineering unit selection, station ID setting, and sensor calibration.

Data downloaded from the WL16 can easily be opened in any spreadsheet program for analysis and graphic presentation. The software will run on a PC-type laptop or desktop computer running Windows 98 or later. The WL16s listed on this page are equipped with a USB port and a cable is included with the free software package.

Available options are: Bluetooth communications, serial port, wastewater or other special sensor. Call or email for details.
