Profile factor Profile Factor
change
10% A change of the profile factor value may be caused by contamination,
blockage or deposits in the line that change the symmetry of the flow
profile.
 We recommend to use the default value.

Symmetry Symmetry
change
10%
A change of the symmetry value may be caused by contamination,
blockage or deposits in the line that change the symmetry of the flow
profile.
 We recommend to use the default value.
SOS differences
between paths
SOS difference
change
1% The SOS deviation indicates whether or not a path is measuring the
correct transit time.
 We recommend to use the default value.
Turbulence Turbulence
change
50%
A change of the turbulence value may be caused by contamination,
blockage or deposits in the line that change the symmetry of the flow
profile.
 We recommend to use the default value.
SNR (Signal-to-noise
ratio)
SNR change 20dB
Interfering noise caused by fittings in the pipeline, valves that are not
fully open, sources of noise near the measuring location, or defective
ultrasonic transducers may affect the signal-to-noise-ratio.
 We recommend to use the default value.
AGC (Signal
amplification)
AGC change 10dB
If the AGCs of a path deviate more than allowed, this can indicate a
malfunction in the ultrasonic transducers, electronic modules,
transducer cables or parameter settings (signal models, control
limits).
 We recommend to use the default value.
