Status Messages - ‘S’:
A number of status messages can be displayed in the 20 character
status message field. They are as follows:
Mode Description
INITIALIZE MODE DSP is acquiring data to calculate a measurement
VF INITIALIZE MODE DSP is acquiring data to calculate a flow measurement
GVF INITIALIZE MODE DSP is acquiring data to calculate a GVF measurement
INVALID SOS DATA DSP is acquiring data to calculate a SOS measurement
BELOW MIN VF QUALITY
Quality of measured sensor data is below a configured
minimum for a Vortical Flow measurement
BELOW MIN SS QUALITY
Quality of measured sensor data is below a configured
minimum for a GVF measurement
BELOW MIN QUALITY
Quality of measured sensor data is below a configured
minimum for VF and SOS measurement
SENSOR OVERLOAD DSP indicates sensors are overloaded
DSP FAILURE - n A DSP communication error occurred

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 speed of sound, 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. Note that the quality field
is not user programmable.
Quality Message Description
VQ or SQ ‘-1 to +1’
Quality metric of the flow (VQ) or Speed of Sound (SQ)
measurement is between –1 and +1; +1 is the most robust
measurement the 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 is usable but not highly reliable
GRN Quality metric is highly reliable
B Band temperature (°C)
T
Process temperature (either from remote sensor or
programmed into system, user selectable °C or F) (if used)
P
Process pressure (either from remote sensor or
programmed into system, user selectable units) (if used)
