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 ToolsSet 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.
