a.Click Start to activate the zero flow calibration. The default duration is four minutes. The status bar indicates the per cent complete. Wait for the
b.When the per cent status shows Completed Successfully, select End Zero to process the results.
c.If you have started the zero flow calibration, select Abort Zero to stop the calibration process without updating the zero flow velocity offset.
d.Click the Next button to display the zero flow velocity offset units of measure.
e.If the one of the following error conditions exists, AMS Device Manager displays an error message and does not update the zero flow velocity offset:
–if the meter has a chord failure
–if the velocity offset is too large
–if the estimated maximum deviation is too large
f.Click Exit to return to the AMS Device Manager - Overview page.
7.On the Overview page, click Alert Setup and select the Flow Analysis tab and enable Reverse Flow (this currently the only parameter available for 3818 LNG Liquid Ultrasonic Flow Meters). Click the OK button to return to the Overview page.
8.On the Overview page, click the Service Tools tab and select the Variables tab. The Flow Data, Path Information, Flow Totals, and All Variables data is populated after you are connected to the meter.
a.Click the Flow Data tab and view the Flow Direction (Forward or Reverse), Average Flow and Average Sound Velocities values.
b.Click the Path Information tab and view the Chord performance, Gain, SNR (Signal to Noise Ratio) Signal strength (mV), and Noise (mV).
c.Click the Flow Totals tab to view the volume totals (forward and reverse uncorrected volume).
