47 Maintenance
47.1 Maintenance Interval
The Type NivuFlow transmitters are conceived to be virtually free of calibration, maintenance
and wear.
NIVUS, however, recommend having the entire measurement system inspected by the NIVUS
customer service once per year.
The maintenance intervals may vary depending on the use case.
Extent and intervals of maintenance depend on the following conditions:
• Material wear
• Process liquid and hydraulic conditions
• General regulations for the operators of the measurement facility
• Ambient conditions
In addition to the annual inspection NIVUS recommends a complete maintenance of the mea-
surement system by one of the legally associated companies and subsidiaries of NIVUS group
after ten years at the latest
.
In general, the inspection of instruments/sensors is a basic measure which helps to increase
operational safety as well as the lifetime.
