6.3.1 General installation rules
DANGER
Risk of injury due to escaping fluids, if pipe connection is faulty
▶
Correct slope and mismatch of pipe connections before inserting the sensor.
Fig. 19:
Avoid: Slope and mismatch
▶
Avoid fixing anything directly to the sensor. Doing so may result in increased devia-
tions.

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