Tip: The .csv and .xml file formats are supported and can be imported by most spreadsheet and database programs.
The data graph can be exported to a .bmp file or a .png file by clicking File > Export >Graph.

Real Time View

Real Time View provides on-screen measurement as data is being recorded by the connected datalogger. A view rate is set independently of the logging period of the Levelogger and does not interfere with internal logging taking place. To take a reading at any specific time, click and that reading will be added to the displayed data. The data can be exported and saved.

Compensate the Data

Click the Data Wizard’ tab to open theData Wizard’ window. In this window the `Wizard’ will guide you through Barometric Compensation, Manual Data Adjustments, and Parameter Adjustments on your open data files. There are two convenient options; Basic or Advanced compensation. This allows you to choose just one, two, or all three types of compensation. Multiple Levelogger files can be barometrically compensated at once, using one open Barologger file.

Tip: `Manual Data Adjustment’ allows you to use manual water level measurements to adjust your data to depth to water readings.

Levelogger Field Measurement

Levelogger 5 Ranges
Each model of Levelogger is rated for a specific submergence depth (Table 1). The choice of model largely depends on the accuracy of the water level required and the submergence depth. The selection, however, should be based on the maximum anticipated water level fluctuation.

Measurement Fundamentals
Levelogger (L) measure the total pressure acting on a transducer at their zero point/sensor. The total pressure is caused by the column of water lying above the Levelogger pressure sensor AND the barometric (atmospheric) pressure acting on the water surface. To compensate for barometric pressure fluctuations and get true height of water column measurements (H), a Barologger (B) is required, i.e.:
Levelogger Reading (L) ­ Barologger Reading (B) = Height of Water Column (H)

Verifying Readings
The best recommendation is to compare barometrically compensated Levelogger data (H) with a manually measured depth to water level value (d) (using a Water Level Meter).

Tip: To adjust all readings in your Levelogger file to depth to water below a well casing (d), record a manual water level measurement using a water level meter. This reading should correspond in date and time with an actual Levelogger recording. Use this as a reference datum in the Manual Data Adjustment option in the Levelogger Software Data Wizard.

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.

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.

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

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

In-field Communication

If you have installed your Levelogger using wireline/Kevlar cord, you can communicate with your Levelogger via a Field Reader 5 or Desktop Reader 5 and Levelogger Software on a laptop PC (you can also use an older style Optical Reader with an L5­Edge DRC Adaptor). If you have installed your Levelogger using an L5 Direct Read Cable, you can communicate with your Levelogger via a PC Interface Cable and Levelogger Software on a laptop PC, using a Levelogger 5 App Interface and the Solinst Levelogger App on your mobile device, or connect an SRU or a DataGrabber 5, without removing the Levelogger from the well.

Maintenance

As with any monitoring project, you should select the proper equipment and determine a maintenance schedule based on the environment specific to your application.

Maintenance tips include:

• Inspect regularly, and replace the ORing at the optical end of the Levelogger if damaged
• Clean the optical eye of the Levelogger with a clean, soft cloth or cotton swab
• Rinse the Levelogger body using a mild, non-residual, non-abrasive household cleaner
• Use a very soft-plastic bristled brush, if needed, to clean the Levelogger body
• Do not insert any object through the circulation holes at the sensor end of the Levelogger
• See the Levelogger User Guide Maintenance Section if simple household cleaners are not sufficient for certain issues, such as hard water build up
• Clean Levelogger 5 LTC conductivity sensor pins before calibration and before/after deployment–see the Solinst Levelogger User Guide
• Stop the Levelogger from recording before storing
• Store Leveloggers with the installation cap on and in the case they were originally provided in
• Store Leveloggers in above-freezing conditions
• Read our Technical Bulletin “Ensuring Proper Use and Maintenance of Leveloggers”

Note: A Solinst Bio foul Screen can be used to protect the Levelogger 5 from biofouling on the pressure sensor, and the conductivity cell of a Levelogger 5 LTC.

Note: All Leveloggers should be deployed and stored with the installation cap or L5 Direct Read Cable attached. This prevents unnecessary battery drainage and protects the optical eye.

Troubleshooting Guide

Levelogger Software:

1. You must have administrator privileges to install software on a computer.
2. The Windows 10 Operating System supports Levelogger Software.

Communication Errors:
“Port Cannot Open”, “Check Com Port”

1. Reason: Software was started before USB device was connected to computer.
   Solution: Restart computer, connect USB device, start software.

2. Reason: Incorrect Com Port is selected in Com Port selection menu.
   Solution: Check the Com Port location for the installed device, by accessing the `Device Manager’ (through the Control Panel), and selecting the “Ports” section. This will state the Com Port the device is installed on.

3. Reason: Another device shares the same Com Port or is causing a communication conflict.
   Solution: Ensure that software for PDA or other devices, which automatically synchronize, are disabled. Ask your system administrator for assistance.

“Communication Time-Out”, “Communication Error”

1. Reason: Levelogger, Direct Read Cable, or communications device has failed. Solution:
   a) Narrow down the failure by using a different Levelogger, Direct Read Cable, or another communications device.
   b) Clean the optical eye/lens on the Levelogger and Optical Reader (Desktop Reader 5 or Field Reader 5), or L5 Direct Read Cable, with a soft cloth.
   c) Check that the communication cable is connected to the same Com Port that is chosen in the upper middle of the Levelogger Software window.
   d) Try using a different computer, to see if this is the cause of the problem.
   e) If using a laptop (especially in conjunction with a Direct Read Cable) your Com Port may not be powered adequately to receive/transmit data. Try using a desktop computer to test this.
   f) If problem persists, contact Solinst.

Frequently Asked Questions
(Also see https://www.solinst.com/products/dataloggers-and-telemetry/3001 -levelogger-series/levelogger-faq/levelogger- faq.php )

How can I protect my Levelogger from corrosive or marine environments?
The Levelogger 5 and Levelogger 5 LTC have a corrosion resistant coating. In harsher chemical environments, you can protect the Levelogger using a thick membrane balloon (e.g. helium) filled with non-corrosive/non-toxic fluid (tap water). As pressure changes, the fluid encasing the dataloggers will transmit the pressure differential to the datalogger’s pressure transducer, without exposing it to corrosive conditions. Continual monitoring is recommended to assess the effectiveness of the protection at your site.

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 (M5) Levelogger 5 or Levelogger 5 Junior 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 a thick membrane balloon filled with a nontoxic, non-corrosive anti-freeze solution or saltwater solution. Place the balloon in a section of perforated, 30 mm (1.25″) ID pipe and install the datalogger 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.

How do I protect my Levelogger from biofouling?
Use the Solinst Model 3001 Bio foul Screen.

Is Levelogger maintenance required?
Yes, consult the Solinst Technical Bulletin “Ensuring Proper Use and Maintenance of Leveloggers” to maintain the long life of your instrument, based on the monitoring environment specific to your application.
