3.5 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.
3.5.1 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.
The length of the loop will add to the Blind Zone. The location of the chuck will determine the
beginning of the Blind Zone. See “Accuracy over measuring range” on page 108 for further
information on Blind Zones.
The Probe Length should be configured as the distance from the Upper Reference Point to the
top of the chuck.
Figure 3-7. Flexible Single Lead Probe with Chuck
A ring (customer supplied) can be attached to the weight in a threaded (M8x14) hole at the end
of the weight. Attach the ring to a suitable anchoring point.
Figure 3-8. Flexible Twin/Single Lead Probe with Weight and Ring
A magnet (customer supplied) can be fastened in a threaded (M8x14) hole at the end of the
weight. The probe can then be guided by placing a suitable metal plate beneath the magnet.
