Configuration
The History option allows data stored in the current value database to be
copied and stored for up to a month in the historical database. The historical
database can be configured to log only the values that need to be logged. The
values are logged in the standard (minute-hourly-daily) time base.
NOTE
The time stamp used for standard logging reflects the time at the end of the
period, not at the beginning. For example: Data collected from 8:00 to 9:00 is
stamped 9:00.
The 3095FC also maintains a 10-minute historical database.
Four types of historical databases are maintained:
• Min/Max Database (see “Meter History")
• Minute Database (see “General History")
• Hourly Database (see “General History")
• Daily Database (see “General History")
Meter History
The Min/Max Database is for viewing only and cannot be saved to a disk file.
A total of fifteen history points may be accessed. For an AGA3 meter run, the
first eight (out of fifteen) history points are pre-configured for flow metering
history and cannot be changed. They are configured as follows:
1. Flowing Minutes Today (Accumulate archive type)
2. DP (Average)
3. Static or Line Pressure (Average)
4. Flowing Temperature (Average)
5. C´ or Integral Multiplier Value (IMV)
6. Pressure Extension or Integral Value (IV) (Average)
7. Instantaneous Flow (Accumulate)
8. Instantaneous Energy (Accumulate)
