Figure 2-5: Meter Monitor (Detailed) view
The following details the information displayed in this dialog box.
• Flow Properties Table - the table at the top of the Meter Monitor dialog box shows basic
information about the condition of the flow in the meter.
• Flow Velocity/Flow Ratios Bar Graph - provides a visual comparison between the
velocities for each chord.
• Chord Speeds of Sound Bar Graph - a visual comparison between the calculated speeds of
sound for each chord.
• Gain/Performance Bar Graph - provides either a visual comparison of the average of the
upstream and downstream gains for each chord or a visual comparison of the average
of the upstream and downstream performance for each chord.
• Signal to Noise Bar Graph - provides a visual comparison between the signal to noise
ratio for each chord direction.
• Meter Status Alarms - provides a visual indication of the meter’s status.
• Gas Comp - this dialog shows the gas composition that can be used by the AGA8 or
AGA10 gas calculations.
• Baseline - this dialog shows the meter’s flow characteristics in comparison to limits
defined for the Continuous Flow Analysis features. This dialog is only available for four
path meters that support a baseline and a valid Continuous Flow Analysis key.
• Run time - displays how long the monitor screen has been collecting data.
• Meter Time - the time displayed is the time from the Ultrasonic meter.
Note
If the time displayed has a yellow background, that is an indication that the meter’s
time is more than 10 minutes apart from the PC’s time.
• Meter Data List - displays read-only data selected from the drop-down list.
