13. Conditions of safe operation
To avoid the danger of electrostatic charge accumulation, in case of the NRM with
antenna/housing options “P” & “M” types (with plastic electronic housing, plastic
antenna enclosure or PP flange) the following safety rule shall be observed:

The measured medium should be an electrostatic conductor and the
electrical resistivity of the measured medium cannot exceed 10 4 Ω.

The speed and the method of the filling and emptying process should be
chosen properly according to the measured medium.

The material of the plastic antenna enclosures can produce static electricity.
The antenna enclosure is allowed to clean only with wet rag.
If the NRM-4 with aluminium housings is installed into a location which requires
‘Ga’ protection level, the units should be mounted that they are protected against
rare occurring impacts and friction effects that may be source of a potential ignition.
Meeting the requirements of the technical process
Please carefully consider that all parts of the instrument which possible to come
into contact with the measured medium – including the transducer, the sealing and
any other mechanical parts – should meet all requirements of the applied
technological process, such as the process pressure, temperature and chemical
effects of the used technologies. In addition, it is necessary to take into account at
devices with PP flange that the PP flange’s mechanical strength is much smaller
than the same sized metal flanges.
Changes or modifications not expressly approved by the manufacturer could
void the user’s authority to operate the equipment.
14. Maintenance
The NRM does not require maintenance on a regular basis. Repairs during or after
the warranty period are carried out exclusively at the manufacturer.
The equipment sent back for repairs should be cleaned or neutralised (disinfected)
by the user!
