Instruction Manual
10401-01026 Rev D
3.2.1. Deployment in Open Water
If the Probe is to be deployed in open water (i.e. a river, lake or the sea), a length of plastic
pipe should first be mounted, then the Probe should be suspended within the pipe so it is
always under water, but not on the bottom where it could become buried by silt. This will
protect the Probe from currents, wave action, and debris.
If required, the Baro logger can also be suspended in the same pipe, provided the cap is
vented and the Baro logger is suspended above the maximum water level line.
3.2.2. Choice of Suspension Cable
It is important to use a non-stretch cable to suspend the submerged logger. If the cable
stretches after deployment, a corresponding level change will be recorded. Braided
stainless steel or Kevlar is recommended.
It is advisable to pull test whatever cable you have chosen to ensure it will not stretch after
installation.
3.2.3. Deployment Depth
Baro loggers must not be submerged!
All other Probes must not be submerged below
twice their rated depths. If any Probe is submerged past this limit, the pressure sensor will
burst and will require replacing. Damage of this kind is not covered by your warranty.
Ideally, the water level Probe should be positioned where it will remain submerged at all
times, but never to a greater depth than twice its depth rating.
3.2.4. Deploying the ABS Logger
•
Measure the distance from the proposed suspension point to the
estimated lowest surface level of the water.
•
Cut a length of cable approximately one meter longer than this
measurement in order to ensure the logger will always remain
submerged.
•
Secure the cable to the logger cap and the suspension point,
preferably using a swaged stainless steel ferrule and a carabiner clip
as shown.
•
If the logger has not been programmed to start logging at some time in
the future, start the logger now using either a LeveLine
®
QuickDeploy
™
Key, a LeveLine
®
Meter or a PC running LeveLink
™
software.
•
When you are certain logging has started, screw the logger firmly into
the logger cap and lower it into the water.
3.2.5. Deploying the Gauge (Vented) Version
Deployment of the gauge or vented version of the LeveLine
®
logger is similar to the ABS
version, but instead of a simple suspension wire, a vented cable must be used.
