Quality Messages ‘Q’:
The Quality Field is a diagnostic field that can be used to view certain
quality values in the transmitter. The factory default is none. If more
than one quality is selected, the transmitter will cycle through each.
The options for display are volumetric flow, pressure and temperature
(if used), band temperature, and a 3-level quality metric. The 3-level
fields represent a Red/Yellow/Green setting for the quality of the
output data. The yellow quality is the bounded value where data can
be considered valid, but is not fully reliable. Red indicates unusable,
and green indicates a good measurement.
Quality Message Description
VF ‘-1 to +1’
Quality metric of the measurement is between –1 and +1;
+1 is the most robust measurement system can make
SOS ‘-1 to +1’
Quality metric of the measurement is between –1 and +1;
+1 is the most robust measurement system can make
RED
Quality metric is below the minimum quality factor entered
into the transmitter or the meter is in startup mode
YEL
Quality metric indicates measurement is usable but not
highly reliable
GRN Quality metric indicates measurement is highly reliable
SPL Sound Pressure Level Average
B Band temperature (°C)
T
Process temperature (either from remote sensor or
programmed into system, °C) (if used)
P
Process pressure (either from remote sensor or
programmed into system, Psia) (if used)
