Installation

Ideal Locations

•
areas where the acoustic emission levels are highest and most consistent
•
where the material impact is greatest
•
areas closest to the point of leakage (e.g. valve body)
•
closest point to source of cavitation (e.g. pump body)

Conditions to Avoid

•
non-metallic surfaces, as these tend to attenuate acoustic emission levels
•
pipes with non-metallic liners as these tend to attenuate acoustic emission levels

Conditions to Consider

•
joints and interfaces attenuate the acoustic emission levels.
•
minimal temperature variation where acoustic emission levels are weak.
•
location should provide sufficient response time in alarm or control circuit. e.g. loss
of bearing lubrication, plug chute detection.
Solids Flow Sensing
Recommended
Good friction between product and
piping. Mount Sensor on the
upstream side of gasket for highest
level of acoustic emission activity.

SITRANS AS 100 – INSTRUCTION MANUAL
Not Recommended
Minimal amount of acoustic emission
activity due to limited friction
between product and piping.
