40 Maintenance
40.1
Maintenance Interval
The Type NivuFlow Mobile transmitters are conceived to be virtually free of calibration, mainte-
nance and wear.
NIVUS, however, recommend to have the entire measurement system inspected by the NIVUS
customer service once per year.
Depending on the area of use the maintenance intervals may vary.
Extent and intervals of maintenance depend on the following conditions:
• Measurement principle of sensors
• Material wear
• Measurement medium 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 meas-
urement system by the manufacturer after ten years the latest.
In general, the inspection of instruments/sensors is a basic measure which helps to increase
operational safety as well as the lifetime.
