Levelogger Series Quick Start Guide
Levelogger Edge Field Measurement
Levelogger Edge 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.
Air only
± 0.05 kPa
5 m (16.4 ft.)
± 0.3 cm (0.010 ft.)
10 m (32.8 ft.)
± 0.5 cm (0.016 ft.)

The Levelogger Edge
can withstand overpressurization 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

Table 1 - Levelogger Edge Ranges
Measurement Fundamentals
Leveloggers (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 measured
depth to water level value (d)
(using a Water Level Meter). The
deployment depth of the Levelogger
(D), minus the manual depth to water
measurement (d), should equal the
compensated Levelogger reading, i.e.:
Deployment Depth (D)
Depth to Water (d)
Height of Water Column (H)
Barologger Edge
A single Barologger can
be used to compensate
all Leveloggers on site,
within a 20 mile/30 km
radius and with every
1000 ft (300 m) change
in elevation. Ensure
that your Barologger
will start logging within
at least 3 hours of your
Levelogger start time.
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.
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
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.
• 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
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.
A Support Hanger
Bracket is available
for supporting and
organizing down well
wires or cords, or for
coiling extra Direct Read
Cable lengths.
After Deployment
After deployment, make
sure you do the following:
• Take a manual depth to
water measurement after
the well has stabilized
(approximately 10
Direct Read
• Take another manual
depth to water
measurement just before
removing the Levelogger
from the well
Levelogger Series Quick Start Guide
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 using a Levelogger App Interface and the
Solinst Levelogger App on your mobile device, without removing the Levelogger from the well.
Note: A Direct Read to Optical Adaptor can be used to directly connect a Levelogger to an App Interface.

Frequently Asked Questions
Solinst Levelogger
App & Interface
(Also see http://www.solinst.com/Prod/3001/Levelogger-FAQ.php)
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 thick membrane balloon (e.g. helium) 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. 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 Levelogger Edge or Levelogger Junior Edge (M5) 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 non-toxic, noncorrosive anti-freeze solution or saltwater solution. Place the balloon 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.
How do I protect my Levelogger from biofouling? Use the Solinst Model 3001 Biofoul 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.
Troubleshooting Guide
Levelogger Software:
1. You must have administrator privileges to install software on a computer.
2. Windows 7, 8, and 10 Operating Systems support Levelogger Software.
Levelogger data has been accidentally erased:
If the Levelogger has been restarted and the old data has not been saved, select the download option
“Recover Previous Log”. This will download your previous data set.
Communication Errors:
“Port Cannot Open”, “Check Com Port”
1. Reason: Solution: 2. Reason: Solution: 3. Reason: Solution:
4. Reason:
Solution: 5. Reason:
Software was started before USB device was connected to computer.
Restart computer, connect USB device, start software.
Incorrect Com Port is selected in Com Port selection menu.
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.
The correct Com Port is not available because the USB driver needs to be installed or updated.
See the USB Installation Guide, or refer to Section 4.1.3 of the Levelogger User Guide.
Another device shares the same Com Port or is causing a communication conflict.
Ensure that software for PDA or other devices, which automatically synchronize, are disabled.
Ask your system administrator for assistance.
RS-232 Adaptor to USB converter is improperly installed.
Note: Not all converters are compatible with all makes and models of computers.
Solution: Reinstall supplied driver for converter device.
“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 “eyes” on the Levelogger and Optical Reader, or 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.
Check the Com Port settings. They should be as follows:
• Bits per second: 9600
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow control: None
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.
Note: All Leveloggers should be deployed and stored with the installation cap or direct read cable attached.
This prevents unnecessary battery drainage and protects the optical eyes.
