NOTE

The probe can be installed in the process through the ball valve
assembly provided that the process pressure is less than 10 bar. This
way, the process does not have to be shut down when installing or
removing the probe. However, if the process is shut down before
removing the probe, the process pressure can be max. 20 bar.

NOTE

When measuring temperature dependent quantities make sure that the
temperature at the measurement point is equal to that of the process,
otherwise the moisture reading may be incorrect.
