Fault description

Cause

Rectification

Measured value fluctuates
around 10 … 20 %

Level

time

Various echoes from an uneven medi-
um surface, e.g. an extraction funnel

Check parameter "Material Type" and
adapt, if necessary

Reflections from the medium surface
via the vessel wall (deflection)

Optimize installation position and sen-
sor orientation

How to proceed if a repair is necessary

If a repair should be necessary, please contact your contact person.
