The FB2200 features expanded and flexible history

capability to ensure measurement confidence and

meet the increasing demands for secure data.

The flow computer has four standard periodic logs

available providing hourly, daily, weekly, and monthly

history. These logs can contain up to 110 variables

including flow weighted average data, totals, and gas

composition. For averaging, the FB2200 supports

either flow weighted or flow dependent which can be

linear or formulaic.

For gas meter averages, you can choose between flow

dependent linear per API Chapter 21.1 (2013) or flow

dependent formulaic, flow-weighted linear, or flow

weighted formulaic averages per API Chapter 21.1

(1993). Liquid meter averages are flow-weighted

averages per API Chapter 21.2 (2000).

The default history in the FB2200 can store the

following standard periodic logs for 60 variables. With

the flexible history design, the number of variables and

the time duration for different periodic logs can be

adjusted to meet the application requirement.
