Follow these steps to install the Levelogger using
stainless steel wire and
hooks
:
1) Loop the cable through the coil 2 of the hook assembly, then wind the
looped strands several times around the hook shaft and pass through coil 1.
2) Pass coil 3 through the Well Cap eyelet or Levelogger/Barologger eyelet
and snap coil 3 to the hook shaft.
3) If the Well Cap is not used then some secure tie-off point should be used
or installed.
4) If installing a Barologger, ensure the suspension level is above the highest
expected water level.
5) When retrieving data and/or reprogramming the Levelogger, extract it
from the monitoring location, un-thread the installation cap, interrogate
and re-suspend the unit rechecking the security of the wireline clamps
each time.
The wireline is a multi-stranded 304 Stainless Steel wire with a break
strength of about 40 lbs.
It is recommended that the
Kevlar cord
be connected to the Levelogger
and well cap using a bowline knot (see Figure 10-6). The Kevlar cord is
comprised of multiple Kevlar strands braided with black polyester, and has
break strength of 150 lbs. Kevlar is very suitable for underwater applications
in freshwater and marine environments, as the material resists rusting.
