Coaxial probe.
The Coaxial probe can be guided by
a tube welded on the tank bottom.
Tubes are customer supplied. Make
sure that the probe can move freely
in order to handle thermal expansion.
Rigid Twin Lead probe.
The Rigid Twin Lead probe can be
guided to the tank wall by a fixture at
the lower end of the outer rod. The
end piece needs to be moved
accordingly by cutting the center rod.
The length of the rod outside the end
piece will add to the dead zone.
The fixture is customer supplied.
Make sure the probe is only guided
and not fastened in the fixture to be
able to move freely for thermal
expansion.
Flexible Single Lead probe.
The probe rope itself can be used for
anchoring. Pull the probe rope
through a suitable anchoring point,
e.g. a welded eye and fasten it with
two clamps.
The length of the loop will add to the
dead zone.The location of the
clamps will determine the beginning
of the dead zone. See section "Dead
Zones" on page 2-7 for further
information on Dead Zones.
