Terminology
In order to better understand this product manual, please be aware of the following terminology
and formatting usage.
Bolded terms (i.e. bold) indicate either a keyboard key, a word or icon that appears on your com-
puter monitor screen or a phrase to be emphasized. Context will dictate which is indicated.
Since it is assumed that users of this manual are familiar with mouse usage, many mouse opera-
tions are implied. The term “click” or “clicking” means to press and release the left mouse button.
Similarly, “double-click” means to press and release the left mouse button twice in quick succes-
sion. For example, the phrase “Click the start button” should be interpreted as “Move the mouse
pointer to the task bar and click the start button.” If any other mouse button is used in an opera-
tion, it will be specified in the documentation.
The term “select” means to move the mouse pointer over the indicated target. For example the
phrase “Select Toolbars from the View menu” means to move the mouse pointer over Toolbars
after the View menu has been displayed. “Select” is normally used when the mouseover action
will cause additional menus to display.
The →symbol is used with submenu operations where the user should click the first and last
items in the string separated by →. For example, the phrase “Click on File →New →Folder”
means click on File, select New and click on Folder.
When the documentation directs you to exit a program or window, you can generally do so by
clicking the xgraphic in the upper right-hand corner or by clicking File →Exit.

Introduction
The WL15 Water Level Logger
Congratulations on your purchase of the Global Water WL15 Water Level Logger. This instrument has
been quality tested and approved to provide accurate and reliable water level (water pressure) measure-
ments. We are confident you will find the WL15 to be a valuable asset for your applications. Should you
require assistance, our technical staff will be happy to help.
The WL15 provides a datalogger with a submersible pressure transducer for remote monitoring and re-
cording of water level, flow or pressure data. This highly reliable and accurate water logger records 24,400
readings and is programmable from one reading per second to one reading per day. Ranges of 0-3', 0-15', 0-
30', 0-60', 0-120' and 0-250' are available. A 25' cable is standard, and optional cable lengths are available
up to 1000'.
The WL15’s datalogger is housed in a weather-resistant cylindrical enclosure that slips inside a 2-inch pipe.
The logger is easily adapted with standard hardware for well head mounting or other installations. The
WL15 includes Windows-based software, allowing easy upload of data to standard spreadsheet programs
on a PC computer.
The WL15's level sensor electronics are fully encapsulated with marine-grade epoxy, providing superior
moisture protection over O-ring seals. During this process, the vent tube is sealed directly to the sensing
element, preventing any moisture from damaging the sensor’s electronic components.
The level sensor uses a unique silicon diaphragm to interface between the water and the sensing element.
This silicon diaphragm is highly flexible and touches the sensing element, producing a sensor with excep-
tional linearity and very low hysteresis. The pressure transducer utilizes a stainless steel micro-screen cap to
protect the sensing element. This protective cap has hundreds of openings, making fouling the sensor with
silt, mud or sludge virtually impossible.
