Verification and adjustment cannot be carried out if the following process conditions are
present:
• Gas pockets
Ensure that the system has been sufficiently flushed with the medium. Repeat flushing
can help to eliminate gas pockets
• Thermal circulation
In the event of temperature differences (e.g. between the measuring tube inlet and
outlet section), induced flow can occur even if the valves are closed due to thermal
circulation in the device
• Leaks at the valves
If the valves are not leak-tight, flow is not sufficiently prevented when determining the
zero point
If these conditions cannot be avoided, it is advisable to keep the factory setting for the zero
point.
