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 86.
Order codes for specific nozzle nominal
diameters and heights, → ä 90.
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")
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.
