3. LeveLine
®
Deployment
Prior to deployment of any LeveLine
®
Logger, be sure to connect it to either a PC running
LeveLink
™
software or to a LeveLine
®
Meter and to set up your desired logging start time,
duration and logging rate.
If you do not set the LeveLine
®
Logger up, it will not log any
data!
3.1. Identifying the LeveLine
®
Type and Depth Rating
It is extremely important to identify your LeveLine
®
Probe depth rating prior to deployment.
Deploying a Baro Logger under water will cause the pressure sensor to be overloaded and
damaged. Similarly, deploying a water level Logger deeper than its maximum rating will
cause overload damage.
To identify your LeveLine
®
Probe's depth rating, remove the black end cap, or in the case of
the -CTD version, the black nose sleeve, and look at the label fitted onto the end of the
Logger. The label will show the Logger type (ABS or Gauge) and maximum depth rating (in
meters).
After identifying your Probe's type and depth rating, replace the end cap or nose sleeve and
follow these simple rules:
•
Never deploy a Baro Logger below the surface of the water.
•
Never deploy a water level Logger deeper than its maximum rating.
•
Never deploy a water level Logger where the water is liable to freeze.
•
If deploying a Gauge type Logger, always use a vented cable.
3.2. Deploying the ABS and Baro Versions
The absolute (ABS) and Baro versions of the LeveLine
®
Probes are
extremely easy to deploy as they do not require a vented cable.
ABS and Baro loggers are usually used in conjunction with one another.
Level data obtained from the submerged ABS logger is corrected for
changes in atmospheric pressure in LeveLink
™
by comparison to
barometric pressure logged during the same period with a Baro Logger.
On a site where there are several ABS loggers deployed, there is only
need for one Baro logger.
The diagram to the right shows a typical borehole installation with the ABS
logger submerged and the Baro logger suspended above the maximum
water level line.
Please note, in this case the well or borehole cap must be ventilated in
order to allow the Baro logger to register the true barometric air pressure.
Important:
Always install the LeveLine
®
Loggers vertically with the suspension cap
at the top as shown in the diagram above.
Water level measurements are made at the
row of holes positioned around the bottom of the black end cap/sleeve. Use these holes as
a reference point for measuring deployment offsets.
