Frequently Asked Questions
How can I protect my Levelogger from corrosive or marine environments?
The Levelogger Edge has a corrosion resistant Titanium-based coating. In harsher chemical environments, you
can protect the Levelogger using a thin latex balloon filled with non-corrosive/non-toxic fluid (tap water). As
pressure changes, the fluid encasing the loggers will transmit the pressure differential to the logger’s pressure
transducer, without exposing it to corrosive conditions.
How do I install my Levelogger in a surface water application?
For installations within rivers, streams, wetlands, lakes and watershed or drainage basin monitoring, the shallow
pressure range Levelogger Edge (M5/F15) or Levelogger Junior (M5/F15) should be considered. For installation
in streams or rivers, stilling wells can be constructed which shield the instrument from the water turbulence.
Alternatively, Leveloggers can be lowered into a protective pipe or casing and then attached to a permanent
fixture such as a bridge, pier or hand driven marker/rod.
How do I protect my Levelogger from freezing?
To avoid icing/freezing and transducer damage, the easiest method is to lower the transducer to a point in the
water column below the frost line or ice formation depth. In water bodies such as shallow streams, wetlands or
ponds where icing/freezing may penetrate to the bottom, install the Levelogger in a vented stilling well imbedded
into the bottom of the water body beyond the frost line.
If this is not possible, place the Levelogger inside two elongated silicon, rubber or latex balloons filled with a non-
toxic, non-corrosive anti-freeze solution or saltwater solution. Place the balloons in a section of perforated, 1.25"
(30 mm) ID pipe and install the logger in the monitored water. The antifreeze solution will protect the Levelogger
from ice expansion at the pressure transducer, yet transmit any pressure and temperature fluctuations that occur.
In-field Communication
If you have installed your Levelogger using wireline/Kevlar cord, you can communicate with your Levelogger via
an Optical Reader and Levelogger Software on a laptop PC.
If you have installed your Levelogger using a Direct Read Cable, you can communicate with your Levelogger via a
PC Interface Cable and Levelogger Software on a laptop PC, or a Leveloader, without removing the Levelogger
from the well.
