Detail |
Global Water's WL15X now includes Palm Pilot software to simplify field data collection |
The Water Level Recorder's datalogger is housed in a weather-resistant cylindrical enclosure that can slip inside a 2-inch pipe. The data recorder is easily adapted with standard hardware for well head mounting or other installations. The datalogger enclosure also houses an easily replaceable 9 VDC battery, which powers the Water Level Logger and level sensor for one year. Purchase of the WL15X includes Windows-based datalogging software, which allows easy upload of recorded data to standard spreadsheet programs on a PC computer.
The Water Level Logger's level sensor is fully encapsulated with marine-grade epoxy so that moisture can never leak in or work its way down the vent tube to cause drift or level sensor failure (as is the case with other pressure sensors). The submersible pressure transducer uses a unique, highly flexible silicon diaphragm to interface between water and the sensing element. This silicon diaphragm protects the level sensor's electronics from moisture and provides a submersible water level transducer with exceptional linearity and very low hysteresis. The design of Global Water's water level sensor eliminates the issues associated with metal foil diaphragms, which tend to crinkle and stretch out over time causing drift, linearity, and hysteresis problems. The water level sensor is also protected by a stainless steel micro-screen cap, which makes fouling with silt, mud, or sludge virtually impossible.

Global Water Software
Compatible with Microsoft's Windows 95, 98, ME, 2000, NT, and XP

Tabular Display/Printout
Data in standard spreadsheet format
RS232 cable included (connects logger's data port to PC)
The Water Level Logger includes Global Water Datalogger Software, Windows-based software that provies 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. Globlal Water's Datalogger Software will run on a PC-type laptop or desktop computer running Windows 95 or later. To communicate with the Water Level Logger, a computer must be equipped with a standard RS232 serial communication port. Purchase of the Water Level Logger includes a RS232 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' and 0-250' 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.
The Water Level Logger's datalogger 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 recorder can be installed in a PVC pipe with the datalogger enclosure's rim resting on the pipe's edge. For monitoring surface water, the water level logger can be installed in a a protective stilling constructed of PVC pipe. For detailed Water Level Logger installation tips, click HERE.
The Global Water Level Logger can be used for stream and river gauging, flood analyses, monitoring hydrant pressure, monitoring irrigation canals, groundwater monitoring, infiltration/inflow studies, lake and wetland analyses, landfill/hazardous site analyses, pump tests, surface water monitoring, sewer flow monitoring, stormwater studies, weirs and flumes, tide gauge measurements, and much more . . .
