3. AquaTelemetry System Deployment
Prior to deployment of the AquaTelemetry unit, be sure to connect it to a PC running
AquaTelemetry Utility Software and to set up the telemetry parameters.
If you do not set
the AquaTelemetry unit's telemetry up, you will not be able to communicate with it
when it has been deployed in the field!
3.1. Identifying the LeveLine
®
Sonde Type
It is extremely important to identify your LeveLine
®
Sonde type prior to deployment. The
AquaTelemetry unit is designed to work with LeveLine
®
Absolute (ABS) type sondes only.
Gauge type sondes will not give correct level readings.
Also, deploying a water level sonde deeper than its maximum rating will cause overload
damage.
To identify your LeveLine
®
sonde model and depth rating, remove the
end cap and look at the label fitted into the end of the sonde. The label
will show the maximum depth rating and the word ABS or GAUGE.
After identifying your sonde rating, replace the end cap and follow these
simple rules:
•
Never use a GAUGE type sonde with the AquaTelemetry unit.
•
Never deploy a water level sonde deeper than its maximum rating.
•
Never deploy a water level sonde where the water is liable to freeze.
3.2. Deploying the Sonde
The diagram to the right shows a typical borehole installation with the sonde
submerged below the minimum water level line.
Please note, in this case the well or borehole cap must be ventilated in order
to allow the water level to rise and fall freely.
Important:
Always install the LeveLine
®
sonde vertically with the
cable at the top as shown in the diagram.
Water level measurements are
made at the row of holes positioned around the bottom of the end cap. Use
these holes as a reference point for measuring deployment offsets or when
zeroing the level (see section
) if required.
3.2.1. Deployment in Open Water
If the sonde 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 sonde should be
suspended within the pipe, but not on the bottom where it could become
buried by silt. This will protect the sonde from currents, wave action, and
debris.
3.2.2. Deployment Depth
Sondes must not be submerged below twice their rated depths. If any sonde is submerged
past this limit, the pressure sensor will burst and will require replacing. Damage of this kind
is not covered by your warranty.
