Levelogger Field Notes
Before Deployment
Before deployment, make sure you do the following:
• Program your Levelogger, using Levelogger Software, with the correct
project identification, memory mode, sampling regime, time, etc.
Note:
It is useful to synchronize the times of all Leveloggers and
Barologgers being used for the same project.
• Set a future start time, or start the Levelogger if deploying on a wireline/
Kevlar rope (Leveloggers can be started after deployment if using a Direct
Read Cable)
• Determine borehole depth to ensure Levelogger does not touch the bottom
of the well (avoid submergence in sediment)
• Record the deployment depth of your Levelogger
• Use a Solinst Model 101 or 102 Water Level Meter to take a manual depth
to water measurement that will be used to verify Levelogger readings
• Determine the minimum and maximum expected water levels, as
Leveloggers must remain submerged for the entire monitoring period, and
Barologgers must not be submerged
Deployment
• Deploy your Levelogger and Barologger using a direct read cable for down-
well communication, or use an inexpensive wireline or Kevlar cord.
Note:
For information on other types of installations, see the latest
Levelogger User Guide.
• Install the Barologger in a similar thermal environment as the Levelogger
• The Barologger should be suspended beyond the frost line and deep enough
to avoid large temperature fluctuations
• Ensure the Barologger location is vented to atmosphere
Tip
It is recommended to
take a manual water
level measurement
before installing a
Levelogger, shortly after
installation, periodically
during your monitoring
interval, and at the end
of your measurement
period. Use these
measurement to verify
Levelogger readings, and
for data adjustments
later on. Ensure you
take manual readings
as close in time as
possible to a scheduled
Levelogger readings.
After Deployment
After deployment, make
sure you do the following:
• Take a manual depth to
water measurement after
the well has stabilized
(approximately 10
minutes)
• Take another manual
depth to water
measurement just before
removing the Levelogger
from the well

Well Caps
The Model 3001 2"
(or 4” with Adaptor)
Well Cap Assembly
provides a secure
method of installing
your Levelogger using
wireline/Kevlar cord or
Direct Read Cables.
