Measurement recovery
Measurement recovery time
The Measurement Recovery Time (Echo Timeout) parameter controls the maximum time
from when measurement is lost (e.g. due to process conditions such as foam or
turbulence) until it is annunciated. If measurement is recovered within the time specified
by this parameter, then it will not be annunciated.
Measurement recovery handling
By default, the Measurement Recovery Time is set up automatically by the device based on
the transmitter configuration.
It is recommended to leave the Measurement Recovery Handling at default unless
required by your application. A higher value may be entered to increase robustness and
avoid nuisance alarms. Only enter a lower value if lost measurement is required to be
annunciated within a certain time for your application.
Used measurement recovery time
This is the value used by the transmitter.
C.4.2
Signal quality alert
This section applies only to transmitters ordered with Smart Diagnostics Suite (option
code DA1).
Signal Quality is a measure of the product surface echo amplitude compared to the
surface threshold and noise.
The Signal Quality spans from 0 to 10. A low value means that there is a risk for the noise
peak to be mistaken for the product surface peak.
