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 device is resistant to electrostatic discharges of up to
15 kV (30 kV with the ESD protection option
– recommended for solid applications), but it is the
responsibility of the fitter and the user to prevent ESD.
CAUTION!
Install the device at the correct location to measure level correctly and prevent too much
bending and traction. If necessary, attach the probe to the bottom of the tank.
Figure 3-25: Installation recommendations for solids
1 We recommend installation without a nozzle. If not, h ≤50 mm / 2¨.
2 The end of the probe must be more than 300 mm / 12¨ above the tank bottom.
3 Empty space (radius, R
min
) around the probe.
4 The electromagnetic (EM) field generated by the device. It is also the measurement zone of the probe. Make sure that
the EM field is clear of objects and product flow.
5 Ground the tank, the product and the probe (if attached).
6 If possible, put the process fitting ≥300 mm / 12¨ from the tank wall
