12.4.1.1 Avoiding creation of noise
Zero point stability is a prerequisite for exact mass flow measurement. Insufficient
installation may lead to mechanical tensions or flow noise which impact zero point
stability.
Countermeasures to help avoid noise creation:

▶
Avoid fixing anything directly to the sensor. Doing so may result in increased
deviations.

Secure pipes before installing the flow meter.
Avoid damaging the process connections.
Flush new pipes before installing the flow meter to remove foreign matter, such as
shavings or other residues.
Support sensor weight by using soft coupling (silicone or other types of cushioning
materials).
Avoid bending or tensioning the sensor while aligning the pipe.
Avoid reductions or expansions in pipe directly up- or downstream of flow meter.
Avoid placing control valves, apertures or other devices generating noise near the
sensor.
