Maintenance
32.1 Maintenance interval
The transmitters are conceived to be virtually free of calibration, maintenance and wear (re-
quirements of the Industrial Safety Regulations are unaffected).
NIVUS recommends having the entire measurement system inspected by the NIVUS cus-
tomer service
once per year
.
Depending on the area of use the maintenance intervals however may vary.
Extent and intervals of maintenance depend on the following conditions:
•
Material wear
•
Fluid and channel hydraulics
•
General regulations for the operators of the measurement facility
•
Ambient conditions
NIVUS recommends having the measurement system completely be inspected by the manu-
facturer after latest ten years.
Generally the verification of instruments and sensors is a basic measure in order to improve
operational reliability and to increase the lifetime.

sive inspection after latest ten years contact our customer service:
