1. From the Field Setup Wizard - Continuous Flow Analysis Page, choose the desired
settings:
– Flow Limits - The low and high flow velocity limits defines the velocity range in
which the Continuous Flow Analysis features are active. If the meter is flowing
outside this range, the Continuous Flow Analysis features will not generate
alarms. This is because the meter’s flow characteristics can change significantly
at these extremes.
– SOS comparison (requires AGA 8 Detail method to be used) - The SOS
Comparison analysis compares the meter average speed of sound to the AGA 10
calculated speed of sound. If the % difference between these two values is more
than the Sound velocity comparison limit over an hourly average, the alarm will
become active. Enable is used to enable or disable this alarm. This feature will be
disabled if the meter does not support this functionality.
– Liquid detection - Liquid detection identifies when liquids may be present in the
bottom of the meter run base on the meter’s flow characteristics. Standard
deviation limits can be configured to adjust the operation of this function if
necessary but it is recommended to consult with a Daniel service representative
before making any changes. Enable is used to enable or disable this alarm. This
feature will be disabled if the meter does not support this functionality.
– Abnormal profile - Abnormal profile identifies if the meter flow profile has shifted
from the original baseline profile of the meter. This check is performed on an
hourly average of the meter’s flow characteristics and will be set or cleared on an
hourly basis. The limit can be configured to adjust the operation of this function
if necessary but it is recommended to consult with a Daniel service
representative before making any changes. This feature requires that the meter
baseline be set using the
Tools}|Set Baseline Wizard. Enable is used to enable or
disable this alarm. This feature will be disabled if the meter does not support this
functionality.
– Blockage - Blockage identifies a possible blockage of an upstream flow
conditioner. This check is performed on an hourly average of the meter’s flow
characteristics and will be set or cleared on an hourly basis. Limits can be
configured to adjust the operation of this function if necessary but it is
recommended to consult with a Daniel service representative before making any
changes. This feature requires that the meter baseline be set using the
Tools|Set Baseline Wizard. Enable is used to enable or disable this alarm. This
feature will not be disabled if the meter does not support this functionality.
– Internal bore buildup - Internal bore buildup indicates that the flow characteris-
tics have changed indicating a build up on the internal bore of the meter. The
function is checked on a daily basis using the daily logs to identify a long term
trend. This feature requires that the meter baseline be set using the
Tools}Set Baseline Wizard. Enable is used to enable or disable this alarm. This
feature will be disabled if the meter does not support this functionality.
