6.1 Maintenance
Maintenance work of a safety-relevant nature within the meaning of explosion protection may
only be carried out by the manufacturer, his authorised representative or under the supervision
of authorised inspectors.
To maintain proper condition, regular inspections are required for systems in hazardous areas.
The following checks are recommended:
• Checking the housing, the cable entries and the process connections for corrosion and/or
damage.
• Checking the measuring unit and the process connections for leakage.
• Including the flowmeter in the regular pressure test of the process line.
6.2 Dismantling
In order to prevent injury or material damage when replacing the sensor, always observe the
following points:
• Before dismantling, ensure that all the cables leading to the flowmeter are de-energised
themselves and to the ground potential of the explosive area.
• All the relevant process pipes or containers must be depressurised before dismounting the
flowmeter.
• If the process pipes or the container contain products that are harmful to the environment or
to health, implement the appropriate safety measures before dismantling the flowmeter.
• Replace all the seals when reinstalling the device in the process pipe or container.
CAUTION!
Maintenance measures of a safety-relevant nature within the meaning of explosion protection
may only be carried out by the manufacturer, his authorised representative or under the
supervision of authorised inspectors.
WARNING!
Dismantling must be carried out by qualified personnel trained in explosion protection.
