Maintenance / Repair
WARNING
Risk of injury due to process conditions.
The process conditions, e.g. high pressures and
temperatures, toxic and aggressive measuring media, can
give rise to hazards when working on the device.
— Before working on the device, ensure that the process
conditions do not pose any safety risks.
— If necessary, wear suitable 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.
8.1
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:
Please contact Customer Center Service acc. to page 2 for
nearest service location.
8.2
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.
8.2.1
Disassembly of the meter tube
NOTE
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.
— Ensure that the meter tube is not exposed to impacts or
mechanical loads during disassembly.
