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 cord (Leveloggers can be started after deployment if using an L5 Direct Read Cable)
• Determine borehole depth to ensure 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 101 Flat Tape Water Level Meter or Solinst 102 Cable Water Level Meter to take a manual depth to water measurement that will be used to verify Levelogger readings

Deployment

• Deploy your Levelogger and Barologger using an L5 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

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
