Parameter overview with brief description
Description
Displays the current signal strength (0 to 100 dB).
Assessment of the signal strength:
• < 10 dB: bad
• > 90 dB: very good
Displays the ratio of the number of ultrasonic signals accepted
for flow calculation and the total number of ultrasonic signals
emitted.
Displays the current signal to noise ratio (0 to 100 dB).
Assessment of the signal-to-noise ratio:
• < 20 dB: bad
• > 50 dB: very good
Displays the current turbulence.
