Doppler Frequency (Hz) Average FFT Frequency
% Deviation The width of Spectra is used to determine beam
penetration and calibration. The selection of
"Slurry" in Application Data is recommended for
flow rate indication accuracy when the % Devia-
tion is less than 25. For % Deviation above 35 the
use of "Liquid" is recommended.
For applications that continuously have % Devia-
tion between 25 and 35 proper selection of either
Liquid or Slurry can be confirmed by comparison
to a known flow reference.
Signal Peak-to-Peak mV Peak-to-Peak demodulation signal amplitude.
The acceptable range is between 100 and 3200
mV during typical flow conditions. If less than 100
mV, check Sensor type used and mounting con-
figuration. If greater than 3200 mV, try in-line
mounting and/or "detune" Carrier Fx.
FFT s/sec Number of FFTs per second
