Low Limit High Pass Filter Setting
High Limit Low Pass Filter Setting
Noise Level Set Noise Filter Setting
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 %
Deviation is less than 25. For % Deviation above
35 the use of "Liquid" is recommended.
For applications that continuously have %
Deviation 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 transducer type used and mounting
configuration. If greater than 3200 mV, try in-line
mounting and/or "detune" Carrier Fx.
FFT s/sec Number of FFTs per second
FFT Peak Peak FFT Amplitude
Carrier Fx Transmit Frequency code
Display of "F" at No-Flow conditions
It is normal for the digital display to show an "F" for the no flow condition since the lack of
Spectra information during no flow is the same as a fault condition.
