Meas. reliability too low
– The echo/noise ratio
is too small for reliable
measurement
– Check installation and
process conditions
– Clean the antenna
– Change polarisation
direction
– Use instrument with
higher sensitivity

8.4 Rectify faults
The operator of the system is responsible for taking suitable meas-
ures to rectify faults.
Therstmeasuresare:
•
Evaluation of fault messages, for example via the display and
adjustment module
•
Checking the output signal
•
Treatment of measurement errors
Further comprehensive diagnostics options are available with a PC
with PACTware and the suitable DTM. In many cases, the reasons can
bedeterminedinthiswayandfaultsrectied.
The below tables show typical examples of application-related meas-
urementerrorswithliquids.Themeasurementerrorsaredierentiated
according to the following:
