Solinst Levelogger 5 Series Quick Start Manual page 7

Note: The Levelogger 5 can withstand over-pressurization of 2 times the intended range,
e.g. a Model M10 can accommodate a fluctuation of 20 meters or 60 feet and still
record pressure. However, over-range accuracy is not guaranteed.
Levelogger Field Notes
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 measurements 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 reading.
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 cord
(Leveloggers can be started after deployment if using an L5 Direct Read Cable)
• Determine borehole depth to ensure the Levelogger does not touch the bottom of the well
(avoid submergence in sediment)
• Determine the minimum and maximum expected water levels, as Leveloggers must remain
submerged for the entire monitoring period, and Barologgers must not be submerged
• 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
Levelogger 5 Series Quick Start Guide
A single Barologger 5 can be used to
compensate all Leveloggers on site,
within a 30 km/20 mile radius and
with every 300 m (1000 ft.) change in
elevation. Ensure that your Barologger
will start logging within at least 3 hours
of your Levelogger start time.
