Maintenance / Repair
WARNING
Risk of injury due to process conditions.
The process conditions, for example high pressures and
temperatures, toxic and aggressive measuring media, can
give rise to hazards when working on the device.
• Before working on the device, make sure that the process
conditions do not pose any hazards.
• If necessary, wear suited personal protective equipment
when working on the device.
• Depressurize and empty the device / piping, allow to cool
and purge if necessary.
CAUTION
Risk of burns due to hot measuring media
The device surface temperature may exceed 70 °C (158 °F),
depending on the measuring medium temperature!
• Before starting work on the device, make sure that it has
cooled sufficiently.
Note
Loss of CE conformity!
For pressure equipment consisting of assemblies, CE conformity
is only for devices in the factory-supplied state.
Components should only be replaced by the manufacturer's
service personnel or an authorized specialist workshop.
Replacing components yourself will render the CE conformity
invalid.
Spare parts
Repair and maintenance activities may only be performed by
authorized customer service personnel.
When replacing or repairing individual components, use original
spare parts.
Note
Spare parts can be ordered from ABB Service.

Cleaning
Soiling of the meter tube and the float will impair the measuring
accuracy of the device. The necessary cleaning interval is
dependent on the operating conditions and must be set
individually.
The meter tube and the float must be removed in order to clean
the device.
When cleaning the exterior of meters, make sure that the
cleaning agent used does not corrode the housing surface and
the seals.
To avoid static charge, a damp cloth must be used for cleaning.
Disassembly of the meter tube
NOTICE
Damage to the float!
Damage to the float due to incorrect disassembly.
• Observe the following points when disassembling the
meter tube and the float!
• The float is precision made. During assembly/disassembly,
ensure that the guide ring and the measuring edge are not
damaged. A damaged float causes inaccuracies in the
measurement and can cause damage to the meter tube
under certain circumstances.
• Make sure that the meter tube is not exposed to impacts or
mechanical loads during disassembly.
