6.2 Dismantling
Replacing the indicator
Due to the modular structure of the variable area flowmeters, from a safety perspective the
display can be replaced with identical KROHNE spare parts.
In this case, the measuring tube can remain in the pipeline. This also applies for pressurized
pipes.
Exchanging the entire device
CAUTION!
There may be a loss of measuring accuracy!
CAUTION!
•
Pressurized pipes have to be depressurized before removing the measuring unit.
• Avoid uncontrolled discharge of residual fluid from the measuring unit.
• Where environmentally critical products are concerned, carefully decontaminate the wetted
parts of the measuring tube after dismantling.
• Removal and installation are the responsibility of the operator.
