10 Maintenance / Repair
Repair and maintenance activities may only be performed by authorized customer service
personnel.
When replacing or repairing individual components, original spare parts must be used.
Warning - Potential damage to parts!
The electronic components of the printed circuit board can be damaged by static electricity
(observe ESD guidelines).
Make sure that the static electricity in your body is discharged before touching electronic
components.
When the housing is open, EMC protection is limited.
The flowmeters do not require any maintenance if they are used as intended under normal
operating conditions. It is sufficient to check them following the instructions in this section.
Warning - General risks!
Explosion-proof flowmeters must either be repaired by the manufacturer or approved by a
certified expert following repair work. The relevant safety precautions must be taken before,
during, and after repair work.
Only disassemble the flowmeter to the extent necessary for cleaning, inspection, repairs, and
replacement of damaged components.
10.1 Maintaining the flowmeter sensor
Essentially no maintenance is required for the flowmeter sensor. The following items should be
checked annually:
• Ambient conditions (air circulation, humidity)
• Seal integrity of the process connections
• Cable entry points and cover screws
• Operational reliability of the supply power feed, the lightning protection and the grounds
10.2 Cleaning
When cleaning the exterior of meters, make sure that the cleaning agent used does not corrode
the housing surface and the seals.
