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. Four sample modes: 10 times per second, timed, logarithmic, and exception CE Certified User friendly software included USB and Serial communication options available Serial version is telemetry compatible PDA software simplifies field data collection No need to remove sensor for data collection or battery change Highly accurate water level measurements User programmable start and stop alarms, engineering units, and field calibration setup Unique 0-3 ft range for shallow water Wet-wet transducer eliminates vent tube concerns Automatic barometric pressure and temperature compensation 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 and PDA software, allowing easy upload of data a laptop, desktop or PDA for transfer to spreadsheet programs. NOTE: The Palm operating system is NOT supported. 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.
