ZFC K03/0522
The ZFC does not require special maintenance unless it is used in low-
temperature applications or surroundings with high humidity (above 90% annual
mean). It is the user’s responsibility to take all precautions to dehumidify the
internal atmosphere of the ZFC in such a way that no condensation will occur,
e.g. to put a dose of desiccant (drying agent) inside the enclosure just before
closing it.
Furthermore, it is required to replace the desiccant periodically as advised by its
supplier.
Check periodically:
The condition of the enclosure, cable glands and front panel.
The input/output wiring for reliability and aging symptoms.
The process accuracy. As a result of wear and tear, re-calibration of the
flowmeter might be necessary. Do not forget to re-enter any subsequent K-
Factor alterations.
Clean window and enclosure only with a lint-free cleaning cloth made damp
with a mild soap solution. Do not use any aggressive solvents as these might
damage the coating.
