1.1 Levelogger Series
1.1.1 Levelogger Edge
The Levelogger Edge is an absolute (non-vented) datalogger, which measures
groundwater and surface water levels and temperature. Water levels are displayed
as temperature compensated pressure readings, and can be barometrically
compensated with the aid of a Barologger Edge.
NOTE
The Model number refers to the
depth of submergence below
water level that the pressure sensor
can withstand. i.e.: The Levelogger
Edge, which is available in F7 (M2),
F15 (M5), F30 (M10), F65 (M20),
F100 (M30) and F300 (M100)
ranges has actual water level
ranges of 6.6 ft (2 meters),
16.40 ft (5 meters), 32.80 ft
(10 meters), 65.60 ft (20 meters),
98.40 ft (30 meters) and 328.0 ft
(100 meters), respectively.
NOTE
To use the Levelogger Edge with
Software Version 4.0.3, ensure you
are using version 3.002 firmware.
