Anchor the probe

In turbulent tanks it may be necessary to fix the probe. Depending on the probe type,
different methods can be used to guide the probe to the tank bottom. This may be needed
in order to prevent the probe from hitting the tank wall or other objects in the tank, as well
as preventing a probe from breaking.
Flexible single/twin lead probe
The flexible single lead probe itself can be used for anchoring. Pull the probe rope through
a suitable anchoring point, e.g. a welded eye, and fasten it with a chuck.
