head transversely against the direction of the process flow.

3. Make sure that the temperature at the measurement point is equal to that

of the process, otherwise the moisture reading may be incorrect.

NOTE

The probe can be installed in the process through the ball valve

assembly provided that the process pressure is less than 10 bars. This

way, the process does not have to be shut down for installing or

removing the probe. However, if the process is shut down before

removing the probe, the process pressure can be max. 20 bars.
