Maintenance
BNA…EX bypass level indicators require no maintenance if used as intended. However, they must
be subjected to a visual inspection within the framework of regular general inspections and must
be included in container pressure tests.
Important!
The float is designed for the medium density level indicated on the type plate. Use in
fluids with a different specific gravity results in measurement deviations.
The medium to be monitored should not contain any soiling or coarse particles.
It should also not tend to crystallize out.
The magnetic roller display and attached magnetic switch must be positioned and set using the
enclosed float prior to installation.
The bypass level indicator must not be installed near strong electromagnetic fields (at least 1 m
away).
Correct functioning of the bypass level indicator can only be guaranteed if original KSR Kuebler
accessories and replacement parts are used.
