Section 3. MST/WLS Installation
3.4 WATER LEVEL
SENSOR
The water level sensor probe, with integrated temperature elements, is
attached at the lower end of the flexible protection tube. A weight is attached
to stabilize the tube as illustrated in Figure 3-4:

sensors
As an option, the tube may be stabilized by putting a concentric weight above
the WLS probe, instead of at the end, in order to ensure that measurements
are performed as close to the tank bottom as possible. Also, the eyebolt at the
end of the tube can be removed.
