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.
