Parameter overview with brief description
Parameter Description User interface
Signal strength Displays the current signal strength (0 to 100 dB).
Assessment of the signal strength:
• < 10 dB: bad
• > 90 dB: very good
Signed floating-point number
Acceptance rate Displays the ratio of the number of ultrasonic signals accepted
for flow calculation and the total number of ultrasonic signals
emitted.
0 to 100 %
Signal to noise ratio 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
Signed floating-point number
Turbulence Displays the current turbulence. Signed floating-point number
