A long stud - 10 in. (250 mm) - is recommended for single flexible probes in a
tall nozzle.
Figure 3-3. A single flexible
probe with a long stud.
NOTE!
For single lead probes, avoid 10-in. (250 mm)/DN250 or larger diameter
nozzles, especially in applications with low dielectric constant. An alternative
is to install a smaller nozzle inside the nozzle.
Installation of Single
Lead Probes in
Non-metallic Vessels For optimal single lead probe performance in non-metallic (plastic) vessels,
the probe must be mounted with a metal flange, or screwed in to a metal
sheet (d>8 in./200 mm), if the threaded version is used.

non-metallic vessels.
Electromagnetic disturbances should be kept to a minimum since they may
affect measurement performance.
