Check gas composition, pressure and temperature.
Create a Diagnosis Session according to
 pg. 198, 7.3 and contact your trained
staff or your local SICK representative.
Different speed of sound
in the individual paths
Faulty transducer or
electronic module
Create a Diagnosis Session according to
 pg. 198, 7.3 and contact your trained
staff or your local SICK representative.
Trained staff: Replace the transducer(s) (see Service Manual, Chapter 7).
Note:
Temperature-induced stratification can result in differences between the individual
paths, especially with very low flow (higher temperatures generate higher speeds of
sound). Even if the plant is being filled or if it is shut down, different speeds of sound
may occur in the individual paths as a result of stratification.
Lower signal-to-noise
ratio and reception sen-
sitivity
Increased number of
rejected measurements
in individual paths
Damaged transducer Create a Diagnosis Session according to
 pg. 198, 7.3 and contact your trained
staff or your local SICK representative.
Trained staff: Replace the transducer(s) (see Service Manual, Chapter 7).
Additional sources of
noise due to a valve that
is not fully open, fit-
tings, noise sources
near the device
Check the measurement plausibility and number of rejected measurements and, if
necessary, eliminate noise sources.

Transducer(s) are dirty Create a Diagnosis Session according to
