Average flow measurement report
$RDAVG,S1*CSUM<CR><LF>
$RDAVG:
The keyword sent on the beginning of the report. This sentence reports
smoothed flow measurement. This is the preferred reading, since it filters
out minor fluctuations in flow speed reading due to waves.
S1:
The measured surface velocity with additional average filter applied
(velocity is reported as velocity*10 for m/s, km/h, mph, fps and fpm and as
velocity*1 for mm/s and cm/s). Geolux Instrument Configurator internally
handles the multiplication factor and displays the correct values to the user
CSUM:
The check sum of the characters in the report from $ to * excluding these
characters.
Tilt angle report
$RDANG,A*CSUM<CR><LF>
$RDANG:
The keyword sent on the beginning of each angle report.
A:
Device tilt angle in degrees, as measured by the internal tilt angle sensor.
The angle is relative to the horizontal plane.
CSUM:
The check sum of the characters in the report from $ to * excluding these
characters.
Signal to noise ratio (SNR) report
$RDSNR,S1,S2*CSUM<CR><LF>
$RDSNR:
The keyword sent on the beginning of each SNR report.
S1:
Signal to Noise Ratio of the detected signal in dB. SNR is the difference
between signal level corresponding to measured velocity and the noise
floor level. Low SNR levels indicate that the measured value may be
inaccurate.
S2:
The average Signal to Noise Ratio of the detected signal. SNR is the
difference between signal level corresponding to measured velocity and the
noise floor level. Low SNR levels indicate that the measured value may be
inaccurate.
CSUM:
The check sum of the characters in the report from $ to * excluding these
characters.
Quality of signal report
$QOS,Q1,Q2*CSUM<CR><LF>
$QOS:
The keyword sent on the beginning of each quality of signal report.
Q1:
This is an indicator of the Quality of the Service (measurements) related to
the instrument vibrations. If the instrument is vibrating, the
measurements may be incorrect, and the amount of vibrations is measured
