Confidence (3.2.9.2.)
Indicates echo reliability: higher values represent better echo quality. The display shows the
echo confidence of the last measurement. Echo Threshold (2.12.2.2.) (Page 220) defines the
minimum criterion for echo confidence.
Values (view only)
Range: -20 to 128
In SIMATIC PDM, open the menu Device – Echo Profile Utilities and click on the tab Echo
Profile.
Echo Strength (3.2.9.3.)
Displays the absolute strength (in dB above 1 μV rms) of the echo selected as the
measurement echo.
Values (view only)
Range: -20 to 128 dB
In SIMATIC PDM, open the menu Device – Echo Profile Utilities and click on the tab Echo
Profile.
Noise Average 3.2.9.4.)
Displays the average ambient noise (in dB above 1 μV rms) of a noise profile after each
measurement.
The noise level is a combination of transient acoustic noise and electrical noise (induced into
the transducer cable or receiving circuitry). See Noise Problems (Page 276).
Noise Peak (3.2.9.5.)
Displays the peak ambient noise (in dB above 1 μV rms) of a noise profile after each
measurement.
9.3.3 Maintenance (3.3.)
