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 four 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 feet of water level change.  A 25 ft vented cable is standard on all water level loggers, and optional cable lengths are available from the factory up to 2000 ft.

The WL16, Water Level Logger, is housed in a weather-resistant cylindrical enclosure, which slips inside a standard 2-inch PVC pipe.  The Water Level Recorders are easily adapted with standard hardware for wellhead mounting, stream, or other installations.  Two internal 9 VDC Alkaline batteries will typically power each of the Water Level Loggers for approximately one year even if one of the batteries fails.  A third onboard lithium battery ensures your data is safe in the event both 9V batteries fail.  All Water Level Loggers include Windows, allowing easy upload of data to a laptop, or desktop for transfer to spreadsheet programs. 

The WL16, Water Level Logger's vented submersible pressure transducer is fully encapsulated with marinegrade epoxy.  The electronics are encapsulated so that moisture can never leak in through O-ring seals or work its way into the vent tube and cause drift or sensor failure, as is the case with many other vented sensors.  The vent tube is sealed directly to the wet-wet sensing element, and any moisture that may enter the vent tube from the housing will only contact the ceramic parts, not the electronics.  Most federal agencies, universities, and environmental consultants recommend vented water level sensors for the best monitoring results.

Warning: Non-vented water level loggers may have readings with errors of up to 10 inches due to barometric pressure changes.  Global Water's Water Level Loggers use vented cable to prevent this issue from affecting your data.  To learn more about how barometric pressure can affect your data click HERE.

The vented submersible pressure transducer uses a unique silicon diaphragm to interface between your water and the sensing element.  The diaphragm is highly flexible and touches the sensing element, producing a sensor with exceptional linearity and very low hysteresis.  A stainless steel micro-screen cap protects the pressure transducer diaphragm.  The micro-screen cap has hundreds of openings, making fouling the sensor with silt, mud or sludge virtually impossible.

Software & Firmware

Software & Firmware

The Water Level Logger includes Global Water Datalogger Software, Windows-based software that provides many useful features, such as real-time readout, measurement interval and engineering unit selection, station ID setting, and sensor calibration.  The software makes accessing stored data and setting options easy.  Data downloaded from the Water Level Logger can easily be opened in any PC spreadsheet program for analysis and graphic presentation.  Global Water's Water Level Recorder Software will run on a PC-type laptop or desktop computer running Windows 98 or later.  To communicate with the Water Level Logger, a computer must be equipped with a USB communication port. includes a RS232 or USB cable (for communication between the logger and your computer).
