5.8.3 Configure Continuous Flow Analysis parameters
Configure the Continuous Flow Analysis features of the Daniel Ultrasonic meter. This
Daniel MeterLink
Analysis setup was selected on the Startup Page and you have a valid Continuous Flow
Analysis key.
These features require that the meter baseline be set using the Tools > Set Baseline
Wizard.
Flow limits - low and high flow velocity limits.
•
• SOS comparison (requires AGA 8 Detail method to be used) - compares the meter
average speed of sound to the AGA 10 calculated speed of sound.
• Liquid detection - identifies when liquids may be present in the bottom of the meter run
base on the meter's flow characteristics.
Abnormal profile - identifies if the meter flow profile has shifted from the original
•
baseline profile of the meter.
• Blockage - identifies a possible blockage of an upstream flow conditioner.
Internal bore buildup - indicates that the flow characteristics have changed indicating a
•
build up on the internal bore of the meter.
Set Baseline parameters
Select the direction to baseline and what data to use to perform the baseline. The wizard
will step you through setting a baseline in one direction.
It is necessary to baseline the meter in both directions if the meter will be operating in a bi-
directional application. For meters only operating in a uni-directional application, the
meter only needs one baseline. The status message displayed on the Meter monitor
screen about the baseline not being set can simply be acknowledged to clear the alarm for
a flow direction you do not want to baseline.
Setting baselines in two directions is only necessary if the meter is installed in a bi-
directional application. Flow through the meter in one direction can be quite different
from flow through a meter in the opposite direction. This could be because of flow
conditioners, thermowells, or elbows.
(1) If a flow computer or SCADA system is used to write these values to the meter, they do not have to be entered at this time.
