Specifications - Installation and Operating Instructions
Model LDL2-030 Vented Water Level Data Logger
The Model LDL2-030 Vented Water Level Data Logger has a vented
cable and end cap to allow it to automatically compensate for atmospheric
pressure fluctuations. The data logger measures water level up to 30 ft
(9.14 m) and has an internal temperature sensor that accurately records
temperatures between -40 to 176°F (-40 to 80°C). The innovative design
makes it ideal for use in waste water treatment facilities as well as
monitoring well and ground water levels. The battery-powered data logger
can store over 16,000 measurements per channel, and the software allows
for user selectable sampling rates. The easy to use DL700 software allows
the LDL2-030 to be easily started and stopped from a PC or delayed to
start up to six months in advance.
Before the logger is submerged, make sure all caps and parts of the data
logger are tightened to ensure that it is properly sealed. Since the LDL2-
030 is atmospheric pressure compensated, the communications end of
the data logger, (the end with the vented cap and the key ring hole) must
remain above water. Do NOT allow water or other liquids to come into
contact with this end. Tie a secure line to the key ring hole before
submerging.
