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.

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.

Electromagnetic disturbances should be kept to a minimum since they may affect measurement performance.
