The WL16, Water Level Logger, now supports USB cable interface for laptop and desktop data downloading ...
...OR a serial communication port for use with most popular PDA's and telemetry solutions. |
The WL16, Water Level Logger, is a data logger 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 500'.
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. For more information on supported PDA's click HERE.
The WL16, Water Level Logger's vented submersible pressure transducer is fully encapsulated with marine grade 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.
Bluetooth Capability
AK1500 Bluetooth Adaptor was designed to eliminate the need for custom PDA cables to communicate between your PDA and the WL16 Water Level Loggers. The adaptor connects to the Water Level Logger's serial port using the same interface cable provided with the software-cable kit. The interface operates from a single 9 volt battery and is turned on automatically when the cable connects the water level logger and Bluetooth adapter. Because the Bluetooth module consumes power when turned on, it is recommended that the cable be disconnected from the water level logger when not in use. A red LED shows the power status and is on continuously while the adaptor is plugged into the water level logger. There is also a blue LED that shows the status of the Bluetooth connection |
Groundwater Monitoring, stream and river gauging, Lake/Pond Level Analysis, Flood Level Recording, Irrigation Canals, inflow and infiltration studies, Wetland/Estuary Monitoring, Weirs and Flumes, Wave and Tidal Analysis, and MUCH MORE... NOTE: Polyurethane cable is not recommended for use with hydrocarbons or high concentrations of chlorine. Please look at the WL450 Water Level Transmitter to meet the requirements of these types of applications.

| The Water Level Logger includes Global Water Data logger 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 communication port appropriate to the type of water level logger you have, either a standard RS232 serial or a USB host communication port. Purchase of the Water Level Logger includes a RS232 or USB cable (for communication between the logger and your computer). |
| The Water Level Logger's pressure sensor may be placed slightly below the lowest expected water level. Level ranges of 0-3, 0-15, 0-30, 0-60, 0-120, 0-250, and 0-500 ft are available. When ordering, select the level sensor range that will cover the maximum water level change (this is not necessarily the total depth of water). Selecting the smallest water level range possible will ensure the greatest accuracy. he Water Level Logger's data logger is housed in an enclosure that is designed to slip inside a 2-inch pipe and be completely hidden with a standard or locking well cap. For monitoring groundwater, the water level recorders can be installed in a PVC pipe with the data logger enclosure's rim resting on the pipe's edge. For monitoring surface water, the water level loggers can be installed in a a protective stilling constructed of PVC pipe. For detailed Water Level Logger installation tips, click HERE. |
