Installation in nozzles > 150 mm high
If, when installing probes in nozzles
DN40 (1½" )to 250 (10") with nozzle height of
> 150 mm (6"), the probe could touch the lower
edge due to moving materials in the container,
we recommend using an extension rod with or
without centering disk. This accessory consists
of the extension rod corresponding to the nozzle
height, on which a centering disk is also
mounted if the nozzles are narrow or when
working in bulk solids. This component is
delivered separately from the device.
Please order the probe length correspondingly
shorter. For the exact length of the rod see
"Extension rod / Centering", → ä 88.
Order codes for specific nozzle nominal
diameters and heights can be found,
→ ä 88 .
Only use centering disks with small diameters
(DN40 and DN50) if there is no significant
build-up in the nozzle above the disk.

Installation in DN200 (8")and
DN250 (10") nozzles
When installing the Levelflex in nozzles of
> 200 mm (8"), signals are generated by
reflections on the nozzle wall, which can
sometimes lead to faulty measurements in the
case of products with small dielectric constants.
With nozzle diameters of 200 mm (8") or
250 mm (10"), therefore, a special flange with a
"horn adaptor" must be fitted.
Nozzles with nominal diameters greater than
DN250 (10") should be avoided.
If the rope probe is strongly deflected: use an
extension rod/centering HMP40, additionaly.

unavoidable, installation must be carried out in
accordance with the sketch on the right.
