3.7 Installation recommendations for solids
3.7.1 Nozzles on conical silos
We recommend that you prepare the installation when the silo is empty.
DANGER!
Risk of electrostatic discharge (ESD). The instrument is resistant to electrostatic discharges of
up to 15 kV (30 kV with the supplementary ESD protection option - recommended for solid
applications), but it is the fitter's and the user's responsibility to prevent ESD.
CAUTION!
Install the nozzle in the correct position to measure correctly and prevent too much bending and
traction.

The end of the probe must be more than 300 mm / 12" above the tank bottom.
4
Empty space (radius, R
min
) around the probe.
5
